Please assist with the problem below. Addicted to the Internet? The AnnArbor public school officials would like to estimate the population mean daily

Addicted to the Internet? The Ann Arbor public school officials would like to estimate the population mean daily Internet usage time for all Ann Arbor teens. To do so, a large random sample of Ann Arbor teens was selected. Here are the results of their study. The 95% confidence interval for the mean daily internet usage time for the population of all such Ann Arbor teens was found to be (6.7 hours, 9.3 hours). The 99% confidence interval or the mean daily internet usage time for the population of all such Ann Arbor teens was found to be (6.257 hours, 9.743 hours). The Ann Arbor public school officials know that you have some statistical background and would like your opinion. Please read each statement carefully and share with us your opinion. Question 5 Subquestions 15.:0 For the following statement, the Ann Arbor school officials will need the following two items: points 1. Decide if the provided statement is appropriate or not appropriate. 2. If appropriate, explain why this is a correct statement. If not appropriate, provide a correct statement. |~ Statement 1: We estimate the population mean daily Internet usage time for all Ann Arbor teens to be 8 hours with a 95% margin of error of 1.3 hours.

Decide if the provided statement is appropriate or not appropriate. 2. If appropriate, explain why this is a correct statement. II If not appropriate, provide a correct statement Statement 2: If we repeated this sampling procedure 300 times and for each repetition we computed the corresponding 99% condence interval, we would expect 297 of the resulting intervals would each contain the corresponding sample mean daily Internet usage time. 0.5 point(s) 5.d TBD points We were told the results are based on a random sample of Ann Arbor teens. Is the following statement about the remaining assumption correct or not correct? We need to have a sample size n that is large enough, namely that the sample size n is at least 25. 0 Correct 0 Incorrect According to a study, on any given day, teens in the United States spend an average of 9.5 hours using the Internet. The Ann Arbor public school officials would like test the following theories: Ho: 11 = 9.5 hours versus H8: 11 a: 9.5 hours Where the parameter [.1 represents the mean daily Internet usage time (hours) for the population of all Ann Arbor teens. The interns working on this project used R to run this hypothesis test and got a p-value of 0.028. The output has been checked multiple times and the interns feel confident that no computational error was made. The interns would like your opinion about this p-value of 0.028. Does this pvalue make sense for this hypothesis test? Use the two confidence intervals to explain to the interns why the p-value of 0.028 is a reasonable p-value for this test. No answer entered.
