Refer to the Current Allergy & Clinical Immunology (March 2004) study of latex allergy in health care workers, presented in Exercise 8.28 (p. 365). Recall that you tested H0: µ = 20 against Ha: µ < 20, where µ is the mean number of latex gloves used per week by all hospital employees, based on the summary statistics
n = 46, x = 19.3, and s = 11.9.
a. Compute the p -value of the test.
b. Compare the p -value with a = .01 and make the appropriate conclusion.
