A study of n = 46 hospital employees who were diagnosed with a latex allergy from exposure to the powder on latex gloves. The number of latex gloves used per week by the sampled workers is summarized as follows: xbar = 19.3 and s= 11.9. Let μ represent the meannumber of latex gloves used per week by hospital employees. Consider testing H0: μ = 20 against Ha: μ < 20
a. Give the rejection region for the test at a significance level of α = .01
b. Calculate the value of the test statistic
c. Use the results, part a and b, to make the appropriate conclusion
The answer give rejection region and test statistic for Student’s t test of latex allergy data.
