17.28 is the question that needs answerd the other just goes with it please use calculator method thanks **Chapter 17 Exercises**In all exercises that call for P-values, give the actual value if you use software or the P-Value applet. Otherwise, use Table C to give values between which P must fall.**17.28 Student study times.** Exercise 16.19 (page 389) describes a class survey in which students claimed to study an average of \( \bar{x} = 13.7 \) hours in a typical week. Regard these students as an SRS from the population of all undergraduate students at this university. Does the study give good evidence that students claim to study more than 13 hours per week on average?(a) State null and alternative hypotheses in terms of the mean study time in hours for the population.(b) What is the value of the test statistic \( z \)?(c) What is the P-value of the test? Can you conclude that students do claim to study more than 13 hours per week on average? **Chapter 16 Exercises: Student Study Times****Exercise 16.19**A class survey in a large class for first-year college students asked, "About how many hours do you study during a typical week?" The mean response of the 463 students was \(\bar{x} = 13.7\) hours. Suppose that we know the study time follows a normal distribution with a standard deviation \(\sigma = 7.4\) hours in the population of all first-year students at this university.**Tasks:**(a) Use the survey result to give a 99% confidence interval for the mean study time of all first-year students.(b) What condition not yet mentioned must be met for your confidence interval to be valid?
