### Question Completion Status:#### QUESTION 5Suppose among residents of Connecticut, 20% own 2 or more Apple products. We would like to see if this remains true for only Connecticut college students. Given the following hypotheses:\[ H_0: \mu \leq 0.2 \]\[ H_a: \mu > 0.2 \]In a sample of CT college students, we find that 19 out of 100 own 2 or more Apple products. Calculate the resulting p-value for this test.Options are:- a. 0- b. 0.0576- c. 0.6368- d. 0.3632#### QUESTION 6Researchers recently published an article claiming that the average number of hours young people (ages 15-24) spend on their phone per day is 8.5. To test this claim, the market department at Facebook (owner of Instagram, Whatsapp, etc) collected a group of 120 young people and tracked how much time they spend on their phone throughout the day. In this group, Facebook found that the sample mean was 9.0 hours with a sample standard deviation of 2.0 hours.---*Click Save and Submit to save and submit.

After treatment, the sample mean is found to be M = 40.1 with SS = 48. %3| a. How much difference is there between the mean for the treated sample and the mean for the original population? (Note: In a hypothesis test, this value forms the numerator of the t statistic.) b. If there is no treatment effect, how much difference is expected between the sample mean and its population mean? That is, find the standard error for M. (Note: In a hypothesis test, this value is the denominator of the t statistic.) c. Based on the sample data, does the treatment have a significant effect? Use a two-tailed test with a = .05.
