Use the following information to answer Questions 16-20: The belief is that the mean number of hours per week of part-time work of high school seniors in a city is 10.5 hours. Data from a simple random sample of 23 high school seniors indicated that their mean number of part-time work was 11.5 with a standard deviation of 1.4. Test whether these data cast doubt on the current belief. (use a = 0.05) Part d: Determine the p-value for your test. a) Op-value = 0.002419 b) Op-value = 0.112419 c) O p-value = 0.998791 d) Op-value = 0.997581 e) Op-value = 0.001209 Question 20 Your answer is INCORRECT. Use the following information to answer Questions 16-20: The belief is that the mean number of hours per week of part-time work of high school seniors in a city is 10.5 hours.

Test whether these data cast doubt on the current belief. (use a = 0.05) Part e: State your conclusion for your hypothesis test. a) Reject the null hypothesis which states that the mean number of hours per week of part-time work of high school seniors in a city is 10.5 hours in favor of the alternate which states it is different from that value. ) There is not enough information to make a conclusion. c) Fail to reject the null hypothesis. There is not enough evidence to conclude that the mean number of hours per week of part-time work of high school seniors in a city is different from 10.5 hours.CourseWare - Google Chrome casa.uh.edu/CourseWare2008/Root/Pages/CW/Users/Student/Grades/ ViewGradedTest.aspx?id=FDAEA116-8578-4089-A771-186924D1FB74#96 Click Here For Printable Version Question 16 Your answer is INCORRECT.
