Question

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 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 (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) c. Give a practical interpretation of the interval, part (b) A. One can be 95% confident that the average number of latex gloves used per week by all healthcare workers with a latex allergy is in the interval 0 B. One can be 95% confident that latex gloves cause allergies for all who use a number of gloves contained in the interval ° C. One can be 95% confident that the average number of latex gloves used per week by all healthcare workers with a latex allergy is less than the lower boundary of the interval 0 D. One can be 95% confident that the average number of latex gloves used per week by all healthcare workers with a latex allergy is greater than the upper boundary of the interval d. Give conditions required for the interval, part (b), to be valid O A. i. The sample selected was specifically selected from the target population O B. i. The sample selected was randomly selected from the target population O C. i. The sample selected was specifically selected from the target population O D. i. The sample selected was randomly selected from the target population i. The sample size is sufficiently large, that is, n > 30 i. The sample size is sufficiently large, that is, n> 30 ii. The sample size is sufficiently large, that is, n > 1000 i. The sample size is sufficiently large, that is, n> 1000
