Symptoms of a latex allergy include con- junctivitis, hand eczema, nasal congestion, a skin rash, and shortness of breath. Each in a sample of 46 hospital em- ployees who were diagnosed with latex allergy reported on their exposure to latex gloves (Current Allergy & Clinical Immunology, Mar. 2004). Summary statistics for the number of latex gloves used per week are x = 19.3 and s = 11.9. a. Give a point estimate for the average number of latex gloves used per week by all health care workers with a latex allergy... b. Form a 95% confidence interval for the average number of latex gloves used per week by all health care workers with a latex allergy. c. Give a practical interpretation of the interval you found in part b. d. Give the conditions required for the interval in part b to be valid.
