1. health-care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. in a sample of 46 hospital employees who had a latex allergy,
he mean number of gloves used per week were 19.3 with a standard deviation of 11.9.

a. find a point estimate for the population mean number of latex gloves used per week by all
health-care workers with a latex allergy.

b. find a 95% confidence interval for the mean number of latex gloves used per week by all
health-care workers with a latex allergy. then, interpret your interval.
