A study of n=50 hospital employees found that the number of latex gloves used per week by the sampled workers is summarized by x = 23.1 and s = 12.5. Let μ represent the mean number of latex gloves used per week by all hospital employees. Consider testing H0: μ= 27 vs Ha: μ<27 at a level of significance of 0.01
a. Calculate the value of the test statistic.
b. Calculate the observed significance level
c. Use the results, part a and b, to make the appropriate conclusion, in words of the problem
