under what circumstances will the chi-square test for goodness of fit produce a large value for chi-square?
Answers
The chi-square test for goodness of fit will produce a large value for chi-square under the circumstances where the observed frequencies significantly deviate from the expected frequencies based on the null hypothesis.
The chi-square test for goodness of fit is used to determine if there is a significant difference between the observed frequencies in a sample and the expected frequencies based on a specified distribution.
The test compares the observed frequencies in different categories or groups with the expected frequencies under the null hypothesis.
A large value for chi-square indicates a significant discrepancy between the observed and expected frequencies, suggesting that the null hypothesis is not supported.
This can occur in several circumstances.
First, if the sample size is large, even small differences between observed and expected frequencies can lead to a significant chi-square value.
Second, if there are substantial deviations between the observed and expected frequencies in one or more categories, the chi-square value will be large. This could indicate a lack of fit between the observed data and the expected distribution.
Additionally, if the assumptions of the chi-square test are violated, such as independence of observations or expected frequencies being sufficiently large, it can lead to inflated chi-square values.
These violations can distort the results and lead to a larger chi-square value.
In summary, the chi-square test for goodness of fit produces a large chi-square value when the observed frequencies significantly deviate from the expected frequencies, indicating a lack of fit between the observed data and the expected distribution.

Answers
Answer:
10
Step-by-step explanation:
If the decimal is .5 or above, round up to the next whole number. If the decimal is below .5, round down to the last whole number. Because .7 is greater than .5, we round up to 10.
Answer:
10
Step-by-step explanation:
In rounding, we look at the digit one place to the right of what we are rounding to. If that digit that is one place to the right is 5 or greater, we increase our digit by one. If that digit that is one place to the right is 4 or less, we leave our digit as it is.

Answer:
7. x = 38°
8. y = 65°
9. 261° and 81°
Step-by-step explanation:
Finding x:
You can make an equality with (2x +5) and (3x +33) because the value of these angles are the same, so:
2x +5 = 3x -33
2x - 3x = -33 -5
-x = -38
x = 38°
Finding y:
You can find the value of y making another equally, but this time you have to sum (4y -1) with (3x - 33) or (2x +5) and equal it with 180°:
(4y -1)+(2x +5) = 180
4y -1 +2x +5 = 180
4y +2x +4 = 180
We know from the question 7 that x is 38°:
4y +2•(38) +4 = 180
4y - 76 +4 = 180
4y - 80 = 180
4y = 180 + 80
4y = 260
y = 260/4
y = 65
Finding the value of the angles:
You just have to put the value of x and y in their places and make the calculations:
4•65 +1 = 261°
3•(38) -33 = 81°
Which of the following shifts s are found by the naive string matcher in searching for the pattern is in the text Mississippi?

Answers
The shift that are found by the naive string matcher in searching for the pattern is in the text Mississippi are options (b) 1 and (e) 4
The naive string matcher is a simple algorithm for searching a pattern within a text. It works by comparing the pattern with all possible substrings of the text and returning the starting indices of the matches. The algorithm starts by aligning the first character of the pattern with the first character of the text and then checks if all the characters in the pattern match the corresponding characters in the text.
If a mismatch is found, the algorithm moves to the next starting position in the text and repeats the process. The algorithm continues until all possible starting positions in the text have been checked.
Assuming that the pattern being searched is "issi", the shifts found by the naïve string matcher in searching for the pattern in the text "Mississippi" are
shift of 1: "issi" matches at position 1 in the text "Mississippi"
shift of 4: "issi" matches at position 4 in the text "Mississippi"
Therefore, the correct options are (b) 1 and (e) 4

Answers
The new basic feasible solution will have x\ as a non-basic variable and a new basic variable with a value not equal to zero.
When a problem is in canonical form and the associated basic feasible solution is degenerate, this means that one of the basic variables has a value of zero. If the pivot operation is then performed with the basic variable with a value of zero extracted from the basis, the new basic feasible solution will have x\ as a non-basic variable and a new basic variable with a value not equal to zero. This is because the pivot operation involves exchanging the extracted basic variable with one of the non-basic variables. Therefore, the new basic feasible solution will not be degenerate, as the new basic variable will have a value not equal to zero.

Answers
The type of triangle is an obtuse triangle.
Given that a triangle has side lengths of 7, 8, and 12.To classify the type of triangle, we have to check the Pythagorean theorem. As we know that the Pythagorean theorem states that "In a right-angled triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
"Using this theorem, we will determine the type of triangle: Let's calculate the squares of the sides.7² = 49, 8² = 64, 12² = 144. According to the Pythagorean theorem, In the right-angled triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
(Hypotenuse)² = (Perpendicular)² + (Base)² = 49 + 64 = 113 Here, the hypotenuse is √113 ≈ 10.63.As 12² > 7² + 8² and 12² > 7² + 8², the triangle is an obtuse triangle. Thus, the type of triangle is an obtuse triangle.

Answers
The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.
The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.
Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.
Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

The corner Deli operates on an overhead percent of 20% of the selling price, which results on an overhead of $1.25 on the company's private-labeled bags of corn chips. If the corner Deli has a markup of $4.35 on the bag of corn chips, find (a) selling price, (b) net profit, and (c) cost.
Answers
a) The Selling price at a markup of $4.35 on the bag of corn chips is $6.25 b) The Net profit a markup of $4.35 on the bag of corn chips is $3.10 c) The cost at a markup of $4.35 on the bag of corn chips is $1.90.
How to find selling price,net profit, and cost.We can use the following equations to solve for the selling price, net profit, and cost of the corn chips:
(a) Selling price = cost + markup
(b) Net profit = selling price - cost - overhead
(c) Overhead = overhead percent x selling price
Given that the overhead is $1.25 and the overhead percent is 20%, we can calculate the selling price as follows:
Now that we know the selling price, we can use equation (a) to calculate the cost:
(a) Selling price = cost + markup
$6.25 = cost + $4.35
Cost = $6.25 - $4.35
Cost = $1.90
(b) Net profit = selling price - cost - overhead
Net profit = $6.25 - $1.90 - $1.25
Net profit = $3.10
(c) Overhead = overhead percent x selling price
$1.25 = 0.2 x selling price
Selling price = $1.25 / 0.2
Selling price = $6.25
Therefore, the selling price of the corn chips is $6.25, the net profit per bag is $3.10, and the cost is $1.90.

The estimation of 0.000007328 is \(7\times10^{-6\).
What is estimation?Estimation is he ability to guess the amount of anything without actual measurement.
The number (n) is given as:
\(\text{n}=0.000007328\)
Multiply by 1
\(\text{n}=0.000007328\times1\)
