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 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 9.7ad s 118. Complete parts (a)-(d) 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 the average number of latex gloves used per week by all healthcare workers with a latex allergy is 1 the inter al 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 ° C. D boundary of the interval. One can be 95% confident that latex gloves cause allergies for all who use a number of gloves contained in the interval. One can be 95% confident that the average number of latex gloves used per week by all healthcare workers with a latex allergy is ess than the lower boundary of the interval

Explanation / Answer

Part-a

Point estimate=19.7

Part-b

95% confidence interval =19.7-t(0.05,46-1)*11.8/sqrt(46), 19.7+t(0.05,46-1)*11.8/sqrt(46)

=(16.20        23.20)

Part-c

Option-A

Part-d

Option--B
