Multiple choice: Select the best answer for Exercises 25 to 28.
Exercises 25 to 27 refer to the following setting. A sample survey interviews SRSs of 500 female college students and 550 male college students. Researchers want to determine whether there is a difference in the proportion of male and female college students who worked for pay last summer. In all, 410 of the females and 484 of the males say they worked for pay last summer.
The researchers report that the results were statistically significant at the 1% level. Which of the following is the most appropriate conclusion?
(a) Because the P-value is less than 1%, fail to reject \(H_0\). There is not convincing evidence that the proportion of male college students in the study who worked for pay last summer is different from the proportion of female college students in the study who worked for pay last summer.
(b) Because the P-value is less than 1%, fail to reject \(H_0\). There is not convincing evidence that the proportion of all male college students who worked for pay last summer is different from the proportion of all female college students who worked for pay last summer.
(c) Because the P-value is less than 1%, reject \(H_0\). There is convincing evidence that the proportion of all male college students who worked for pay last summer is the same as the proportion of all female college students who worked for pay last summer.
(d) Because the P-value is less than 1%, reject \(H_0\). There is convincing evidence that the proportion of all male college students in the study who worked for pay last summer is different from the proportion of all female college students in the study who worked for pay last summer.
(e) Because the P-value is less than 1%, reject \(H_0\). There is convincing evidence that the proportion of all male college students who worked for pay last summer is different from the proportion of all female college students who worked for pay last summer.
