according to 2015 census data, 42.7 percent of colorado residents were born in colorado. if a sample of 250 colorado residents is selected at random, what is the standard deviation of the number of residents in the sample who were born in colorado?
Answers
The standard deviation of the number of residents in the sample who were born in Colorado is 7.82
Standard deviation:
The measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists is know as standard deviation.
Given,
According to 2015 census data, 42.7 percent of Colorado residents were born in Colorado. if a sample of 250 Colorado residents is selected at random.
Here we need to find the standard deviation of the number of residents in the sample who were born in Colorado.
Here we know that following details,
Number of sample = 250
Estimated proportion for residents born in Colorado = 42.7% which is equal to = 0.427.
Let us consider X be the random variable of interest (number of residents in the sample), on this case we now that:
X ~ (n = 250, p = 0.427)
Now, according to the probability mass function for the Binomial distribution is given as:
E(X) = n x p = 250 x 0.427 = 106. 75.
Now, the standard deviation for the random variable is given by:
SD = √106.75 (1 - 0.427)
SD = √106.75(0.563)
SD = 7.82
Therefore, the standard deviation is 7.82.

In a positively skewed distribution, what order (left to right) will we find the mean, median and more
Answers
So the order from left to right would be: Mode, Median, Mean.
In a positively skewed distribution, the mean is typically larger than the median, and the median is larger than the mode.
This can be illustrated in the following way:
Mean: The mean is affected by extreme values in the tail of the distribution, and will be pulled in the direction of the skew. Therefore, in a positively skewed distribution, the mean will be to the right of the median.
Median: The median is the value that separates the lower 50% of the data from the upper 50% of the data. In a positively skewed distribution, the tail of the distribution is on the right-hand side, which means that the median will be closer to the left-hand side than the mean.
Mode: The mode is the most frequent value in the distribution. In a positively skewed distribution, the mode will be the smallest value, located at the left-hand side of the distribution, while the mean and median will be to the right of it.

six bells commence tolling together and toll at intervals of 5, 10, 15, 20, 25, and 30 second respectively. in 60 minutes, how many times do they toll together?
Answers
If six bells commence tolling together and toll at intervals of 5, 10, 15, 20, 25, and 30 seconds respectively then they will toll together 12 times in 60 minutes.
To find the number of times the bells toll together within 60 minutes, we can calculate the number of intervals where their tolling patterns coincide.
Let's analyze the timing of the bells:
The first bell tolls every 5 seconds.
The second bell tolls every 10 seconds.
The third bell tolls every 15 seconds.
The fourth bell tolls every 20 seconds.
The fifth bell tolls every 25 seconds.
The sixth bell tolls every 30 seconds.
We need to find the number of common multiples of these intervals within 60 minutes (or 3600 seconds).
The least common multiple (LCM) of the intervals is the smallest number that is divisible by all the intervals' values. In this case, the LCM of 5, 10, 15, 20, 25, and 30 is 300.
Now, let's count the number of intervals of 300 seconds within 3600 seconds:
3600 / 300 = 12
Therefore, within 60 minutes, the bells toll together 12 times.

An expression that represents the measure of the third side is 4x.
What is the perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The perimeter of the triangle is 3x² - 7x + 2.
And the measures of the two sides are x² - x - 4 and 2x² - 10x + 6.
The measure of the third side = the perimeter of the triangle - (the total measure of the two sides)
The measure of the third side = 3x² - 7x + 2 - (x² - x - 4 + 2x² - 10x + 6)
The measure of the third side = 3x² - 7x + 2 - (3x² - 11x +2)
The measure of the third side = 4x

It takes Boeing 29,454 hours to produce the fifth 787 jet. The learning factor is 80%. Time required for the production of the eleventh 787 : 11th unit time hours (round your response to the nearest whole number).
Answers
Boeing takes 29,454 hours to produce the fifth 787 jet. With an 80% learning factor, the time required for the production of the eleventh 787 is approximately 66,097 hours.
To calculate the time required for the production of the eleventh 787 jet, we can use the learning curve formula:
T₂ = T₁ × (N₂/N₁)^b
Where:
T₂ is the time required for the second unit (eleventh in this case)
T₁ is the time required for the first unit (fifth in this case)
N₂ is the quantity of the second unit (11 in this case)
N₁ is the quantity of the first unit (5 in this case)
b is the learning curve exponent (log(1/LF) / log(2))
Given that T₁ = 29,454 hours and LF (learning factor) = 80% = 0.8, we can calculate b:
b = log(1/LF) / log(2)
b = log(1/0.8) / log(2)
b ≈ -0.3219 / -0.3010
b ≈ 1.0696
Now, substituting the given values into the formula:
T₂ = 29,454 × (11/5)^1.0696
Calculating this expression, we find:
T₂ ≈ 29,454 × (2.2)^1.0696
T₂ ≈ 29,454 × 2.2422
T₂ ≈ 66,096.95
Rounding the result to the nearest whole number, the time required for the production of the eleventh 787 jet is approximately 66,097 hours.

A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 times Kelly’s. If the total bill is $114.00, how much does each person owe?
Answers
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5

Exponential form is a way of representing repeated multiplications of the same number by writing the number as a base with the number of repeats written as a small number to its upper right.
In the exponential form, the exponent indicates the number of times the base is used as a factor.
For example, in the case of 16 it can be written as 2 × 2 × 2 × 2 = \(2^{4}\), where 2 is the “base” and 4 is the “exponent.
A product in which the factors are identical is called a power of that factor. The number that is repeated is called the base, and the number of times it repeats is called the exponent, power or degree. And the power that is written on the right upper side are called exponents. when multiplying the numbers having same base and different exponents then the base is kept same and the exponents are added.

Ha: at least one μi is different (there is a difference in the mean rating of the pens following exposure to five advertisements)
Where μi is the mean rating for advertisement i.
Test Statistic: F-test, since there are more than two groups being compared.
F = MSR / MSE
where
MSR = (SSG / k-1) is the mean square for regression or the between-group variation, and
MSE = (SSE / n-k) is the mean square for error or the within-group variation
k = number of groups (advertisements)
n = total sample size
P-value: we will use the F-distribution table and the degrees of freedom (k-1, n-k) to find the P-value.

Decision Rule: Reject H0 if P-value < α, otherwise fail to reject H0.
b. We will perform pairwise comparisons between the means of the different groups using Tukey's HSD test (or another appropriate multiple comparison tests) to determine which advertisements differ in mean ratings.
c. Hypotheses:
H0: σ1^2 = σ2^2 = σ3^2 = σ4^2 = σ5^2 (there is no significant difference in the variation of ratings among the five advertisements)
Ha: at least one σi^2 is different (there is a difference in the variation of ratings among the five advertisements)
Test Statistic: F-test, since we are comparing the variances of multiple groups.
F = s1^2 / s2^2, where s1^2 is the larger sample variance and s2^2 is the smaller sample variance.
