Health care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. Each in a sample of 46 hospital employees who were diagnosed with a 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 x overbar equals 19.3 and s equals 12.1 a. Give a point estimate for the average number of latex...

2. An article in Current Allergy & Clinical Immunology (Mar. 2004) studied n = 46 hospital employees who were diagnosed with allergic reactions on their hands and arms. There is some evidence that latex allergies develop from exposure to the powder on latex gloves. The number of pairs of latex gloves used per week by the sampled workers is summarized as follows: ? = 19.3 and s = 11.9. Let μ represent the mean number of pairs of latex gloves...
Health care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. Each in a sample of 40 hospital employees who were diagnosed with a 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 x = 19.3 and s = 12.2. Complete parts (a)-(d). a. Give a point estimate for the average number...
You are testing H0: μ = 100 against Ha: μ < 100 based on an SRS of 21 observations from a Normal population. The data give x̄ = 9.1 and s = 3.6. The value of the t statistic (±0.01) is _______
