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 47 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= 12.3. 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). O A. One can be 95% confident that latex gloves cause allergies for all who use a number of gloves contained in the interval. O B. 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. Oc. 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. O 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 less than the lower boundary of the interval.

Transcribed Image Text: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 47 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 = 12.3. 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.)
с. Gi
a practical interpretation of the interval, part (b).
A. One can be 95% confident that latex gloves cause allergies for all who use a number of gloves contained in the interval.
B. 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.
O 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 in the interval.
O 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 less than the lower boundary of the interval.
d. Give conditions required for the interval, part (b), to be valid.
O A. i. The sample selected was randomly selected from the target population.
ii. The sample size is sufficiently large, that is, n> 30
B. i. The sample selected was specifically selected from the target population.
ii. The sample size is sufficiently large, that is, n> 1000
O C. i. The sample selected was randomly selected from the target population.
ii. The sample size is sufficiently large, that is, n> 1000
O D. i. The sample selected was specifically selected from the target population.
ii. The sample size is sufficiently large, that is, n > 30
