Health care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. Symptoms of a latex allergy include conjunctivitis, hand eczema, nasal congestion, a skin rash, and shortness of breath. Each in a sample of 46 hospital employees who were diagnosed with latex allergy based on a skin-prick test reported on their exposure to latex gloves. Summary statistics for the number of latex gloves used per week are ¯xx¯ = 19.3 and s = 11.9. a. Form a 95% confidence interval for the average number of latex gloves used per week by all health care workers with a latex allergy. b. Give a practical interpretation of the interval you found in part b. c. Give the conditions required for the interval in part b to be valid.
