Answer:
B. 0.0122
Step-by-step explanation:
According to the given data the claim is:
"Proportion of students who went to the movie theater last weekend is greater than 0.2"
Since, the word "greater than" is used in the claim, this claim will be our alternate hypothesis and the hypothesis test will be a one-tailed test i.e. Right tailed test because of the word "greater than".
We are given that the hypothesis test was conducted for a random sample of 100 students and it yielded a z-value of 2.25. We have to find the p-value associated with this z-score
So, we have to find p-value corresponding to z-score of 2.25 and Right Tailed Test. We have to use z-table for this purpose and find the probability of z score being greater than 2.25. From the z-table this value comes out to be:
p-value = 0.0122
Therefore, option B gives the correct answer.
Answer:
The point (-8,7) is the reflection of the point (8,7)
I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.
The best measure for evaluating the relative contributions of the individual predictors in a multiple regression is β.
Obtain the standardized coefficients. Regression Sum up the absolute value of all standardized coefficients. Divide every individual standardized coefficient estimate by using the sum and multiply by one hundred to attain the contribution of every predictor variable.may additionally.
Normally variable with highest correlation is a great predictor. you can also examine coefficients to pick the pleasant predictor additionally look exchange in squared cost. Relative significance is described because the percentage development with admire to the maximum essential predictor. Relative importance is calculated with the aid of dividing every variable importance rating by the most important importance rating of the variables.
