The distribution is not Normal: many house- holds pay a low rate as part of a bundle with phone or television service, but some pay much more for Inter- net only or for faster connections.
A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid.
(a) Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55.
(b) What are the mean and standard deviation of the sampling distribution of ?
(c) What is the shape of the sampling distribution of x? Justify your answer.
(d) Find the probability that the average fee paid by the sample of households exceeds $55. television service, but some pay much more for Inter- net only or for faster connections.
Answers
Answer:
(a) See Explanation
(b) \(\bar x =50\) and \(\sigma_x = 0.8944\)
(c) The shape is normal
(d) \(P(\bar x > 55) = 0\)
Step-by-step explanation:
Given
\(\mu = \$50\) -- mean
\(\sigma = \$20\) --- standard deviation
\(n=500\) --- sample size
Solving (a): The reason we can't determine the probability that an amount to access internet by a household will exceed $55.
The question says that a lot of households pay low rates, but the percentage of the households in this category is not given. This means that it is impossible to determine the shape of the distribution.
Hence, the probability cannot be calculated.
Solving (b): Sample mean and Sample standard deviation
The sample mean estimates the population mean
So:
\(\bar x =\mu\)
\(\bar x =50\)
The sample standard deviation is calculated as thus:
\(\sigma_x = \frac{\sigma}{\sqrt n}\)
\(\sigma_x = \frac{20}{\sqrt{500}}\)
\(\sigma_x = \frac{20}{22.36}\)
\(\sigma_x = 0.8944\)
Solving (c): The shape of the distribution.
We have:
\(n = 500\) --- The sample size
According to Central limit theorem, When the sample size is greater than 30, then the shape of the distribution is normal.
Hence, the shape is normal
Solving (d): \(P(\bar x \ge 55)\)
Calculate the test statistic (t)
\(t = \frac{\bar x - \mu}{\sigma}\)
\(t = \frac{55 - 50}{0.8945}\)
\(t = \frac{5}{0.8945}\)
\(t = 5.590\)
So:
\(P(\bar x > 55) = P(t > 5.590)\)
Referencing the z table, we have:
\(P(t > 5.590) = 0\)
Hence:
\(P(\bar x > 55) = 0\)
A student ran a distance of 3 1/2 miles each day for five days the student ran a distance of 4 1/4 miles each day for the next five days what was the total distance in miles the student ran darrion is five days
Answers
Darrion ran a total distance of 38 3/4 miles in 10 days.
We have,
To find the total distance Darrion ran in 10 days, we need to add up the distance he ran in the first five days and the distance he ran in the next five days.
Distance ran in the first five days
= 3 1/2 miles per day x 5 days
= 17 1/2 miles
Distance ran in the next five days
= 4 1/4 miles per day x 5 days
= 21(1/4) miles
Total distance Darrion ran in 10 days
= Distance ran in the first five days + Distance ran in the next five days
= 17 1/2 miles + 21 1/4 miles
= 38 3/4 miles
Therefore,
Darrion ran a total distance of 38 3/4 miles in 10 days.

Bender Electronics buys keyboards for its computers from another company. The keyboards are received in shipments of 100 boxes, each box containing 20 keyboards. The quality control department at Bender Electronics first randomly selects one box from each shipment and then randomly selects 5 key boards from that box. The shipment is accepted if not more than 1 of the 5 keyboards is defective. The quality control inspector at Bender Electronics selected a box from a recently received shipment of keyboards. Unknown to the inspector, this box contains 6 defective keyboards.
Round your answers to four decimal places.
a. What is the probability that this shipment will be accepted?
P(shipment accepted)=
b. What is the probability that this shipment will not be accepted?
P(shipment not accepted)=
Answers
Answer:
a
\(P(shipment\ accepted) =0.6337 \)\
b
\(P(shipment\ not\ accepted)= 0.3663 \)
Step-by-step explanation:
from the question we are told that
The number of boxes N = 100
The number of keyboard in each box is k = 20
The sample size is n = 5
Generally the number of ways of selecting 1 keyboard from the 5 selected keyboard is mathematically represented as
\(G = \ ^{5}C_1\)
Here C stands for combination (Hence in the question we will be making use of the combination functionality in our calculator )
Generally the number of ways of selecting 0 keyboard from the 5 selected keyboard is mathematically represented as
\(H = \ ^{5}C_0\)
Generally the number of ways of selecting 5 keyboard from the 20 keyboards is mathematically represented as
\(F = \ ^{20}C_5\)
Generally the number of ways of selecting 5 keyboard from the 15 keyboards is mathematically represented as
\(W = \ ^{15}C_5\)
Generally the number of ways of selecting 5 keyboard from the 15 keyboards is mathematically represented as
\(V = \ ^{15}C_4 \)
Generally the probability that a shipment will be accepted is mathematically represented as
Probability of 0 defect out of 5 + Probability of 1 defect out of 5
Now
Probability of 0 defect out of 5 is mathematically represented as
\(P(A_1) = \frac{H*W }{ F}\)
=> \(P(A_1) = \frac{1 *3003 }{ 15504}\)
=> \(P(A_1) = 0.1937\)
And Probability of 1 defect out of 5 is mathematically represented as
\(P(A_2) = \frac{ G * V}{ F}\)
=> \(P(A_2) = \frac{ 5 * 1365}{15504}\)
=> \(P(A_2) = 0.440\)
Generally the probability that a shipment will be accepted is mathematically represented as
\(P(shipment\ accepted) =0.1937 + 0.440\)
=> \(P(shipment\ accepted) =0.6337 \)
Generally the probability that this shipment will not be accepted is mathematically represented as
\(P(shipment\ not\ accepted)= 1 -P(shipment \ accepted)\)
\(P(shipment\ not\ accepted)= 1 - 0.6337 \)
\(P(shipment\ not\ accepted)= 0.3663 \)

That is, change 1171.1 miles into hours of snail travel. USE DIMENSIONAL ANALYSIS TO MAKE YOUR CALCULATION! Include units at each step.
Answers
It will take the snail 40,271.33 hours (time) to travel 1,171.1 miles (distance) at 0.013 meters per second (speed).
How are the hours determined?The hours that it will take the snail to travel the distance is determined by first converting the miles into meters at 1 mile = 1,609.34 meters.
The speed per second is also converted into speed her hour.
The conversions use the mathematical operations of division and multiplication.
Time = distance/speed.
Data and Calculations:Total distance in miles = 1,171.1 miles
Total distance in meters = 1,884,698.07 meters (1,171.1 x 1609.34)
Speed = 0.013 meters per second
Speed in hours = 46.8 meters per hour (0.013 x 60 x 60)
The number of hours to cover the distance = Total Distance/Speed
= 40,271.33 hours (1,884,698.07/46.8)
Thus, it will take the snail 40,271.33 hours to cover a distance of 1,171.1 miles at a speed of 0.013 meters per second.

Consider the spreading of a rumor through a company of 1000 employees, allworking in the same building.We assume that the spreading of a rumor is similar to the spreading of a contagious disease (see Example 3, Section 1.2) in that the number of people hearing the rumor each day is proportional to the product of the number who have heard the rumor previously and the number who have not heard the rumor. This is given by
rn+1 = rn + 1000krn(1000 ? rn)
where k is a parameter that depends on how fast the rumor spreads and n is the number of days. Assume k = 0.001 and further assume that four people initially have heard rumor. How soon will all 1000 employees have heard the rumor?
Answers
Answer:
On the 12th day, the rumor would have has to all the 1000 employees
Step-by-step explanation:
Given the data in the question;
so, lets consider the rumor spreading thorough the company of 1000 employee;
the given model is; \(r_{n+1}\) = \(r_{n}\) + 1000k\(r_{n}\) ( 1000 - \(r_{n}\) )
where k is the parameter that depends on how fast the rumor spreads, n is the number of days.
now, lets assume k = 0.0001, lets also assume r₀ = 4
so to find how soon all 1000 employees will have heard the rumor ;
let n be;
then r1 will be;
r1 = r₀ + ( 0.001)r₀(1000-r₀ )
so
r1 = 4 + ( 0.001) × 4× (1000 - 4 )
r1 = 7.984
r2 will be;
r2 = r1 + ( 0.001)r1(1000-r1 )
r2 = 7.984 + ( 0.001) × 7.984 × (1000 - 7.984 )
r2 = 15.904255744
r3 will be;
r3 = r2 + ( 0.001)r2(1000-r2 )
r3 = 15.904255744 + ( 0.001) × 15.904255744 × (1000 - 15.904255744 )
r3 = 31.555566137
Using the same formula and procedure by substituting n = 1,2,3,4,5,6,7,8,9,10,11,12.
we will have;
n rₙ
0 4
1 7.984

Given two events X and Y: Event X has the probability 5/6. If event X happens, then the probability of event Y is 2/5. If event X does not happen, then the probability of event Y is 1/4. Find the following probabilities:
(a) P(not X)
(b) P(Y|not X)
(c) P(not Y | X)
(d) P(X and Y)
(e) P(not X and not Y)
Answers
The probabilities for each part of the problem are: P(not X) = 1/6 , P(Y | not X) = 3/4 , P(not Y | X) = 3/5 , P(X and Y) = 2/9 , P(not X and not Y) = 1/8.
Probability is a measure of the likelihood of an event occurring. It is expressed as a decimal or fraction between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Given two events X and Y, we can use probability formulas to find the probability of various combinations of these events. For example, if we know the probability of event X occurring (P(X)) and the probability of event Y occurring given that event X has occurred (P(Y | X)), we can find the probability of both events occurring together (P(X and Y)) using the formula P(X and Y) = P(X) * P(Y | X). We can also find the probability of one event occurring given that another event has not occurred using the formula P(Y | not X) = P(Y and not X) / P(not X). We can also find the probability of an event not occurring using the formula P(not X) = 1 - P(X). Using these formulas, we can find the probability of various combinations of events, such as the probability of one event occurring and another event not occurring (P(X and not Y)), or the probability of both events not occurring (P(not X and not Y)).
