Can you help with part e of 7.40? I did all my work except that because I don't know how to use ANTS file for e. Any help would be appreciate.

There is 90% confidence that population mean value of annual rainfall amount at any size in the day steppe region of central asia is between 163.715 and 203.8557.40 Rainfall and desert ants. Refer to the Journal of D Biogeography (Dec. 2003) study of ants and their habitat ANTS in the desert of Central Asia, presented in Exercise 2.68 (p. 63). Recall that botanists randomly selected five sites SC in the Dry Steppe region and six sites in the Gobi Desert where ants were observed. One of the variables of interest is the annual rainfall (in millimeters) at each site. Summary statistics for the annual rainfall at each site are provided in the SAS printout below. a. Give a point estimate for the average annual rainfall amount at ant sites in the Dry Steppe region of Central Asia. b. Give the f-value used in a small-sample 90% confidence interval for the true average annual rainfall amount at ant sites in the Dry Steppe region. c. Use the result you obtained in part b and the values of x and s shown on the SAS printout to form a 90% confi- dence interval for the target parameter. d. Give a practical interpretation for the interval you found in part c. e. Use the data in the ANTS file to check the validity of the confidence interval you found in part c. f. Repeat parts a-e for the Gobi Desert region of Central Asia.
