Hello, Please refer to Introductory Statistics 10e by Neil A Weiss. Thanks

Do Exercises 8.72 on page 349 in the textbook. Preliminary data analyses indicate that you can reasonably apply the z-interval procedure.

1. (a)Find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. Assume a population standard deviation of 190.0. (Note: The sum of the data is 9047).
2. (b)Interpret your answer from part (a).
3. (c)Find a 99% confidence interval for ????.
4. (d)Why is the confidence interval you found in part ( c) longer than the
5. one in part (a)?
6. (e)Draw a graph similar to the one shown in Figure 8.5 to display both
7. confidence intervals.
8. (f)Which confidence interval yields more precise estimate of ????? Explain
9. your answer.
10. Do Exercise 8.73 on page 349 in the textbook. Preliminary data analyses indicate that you can reasonably apply the z-interval procedure.
11. Do Exercise 8.89 on page 350 in the textbook.
12. Do Exercise 8.116 on page 359 in the textbook.
13. Do Exercise 8.131 on page 360 in the textbook. Assume the distribution of additional hours of sleep is fairly normal.
14. Using the data in question 5 of this assignment use Excel to find a 99% confidence interval for the additional sleep that would be obtained on average for all people using laevohysocyamine hydrobromide. Hand in the Excel printout and write the upper and lower limits for the interval in the same printout.
