Question

A study of n 51 hospital employees who were diagnosed with a latex allergy from exposure to the powder on latex gloves found that the number of latex gloves used per week by the sample workers is summarized as follows: x-19.1 and s-8.4. Let ơ2 represent the variance in the number of latex gloves used per week by all employees. Consider testing o100 against Ha of #100. Complete parts a through c. a. Give the rejection region for the test at a significance level of α = 0.01. Choose the correct answer below. OA. 굿>77 3860 O c. x2<27.9907 or2>79.4900 (JE 30.4750 SX2 < 77.3860 O G. 230.4750 b. Calculate the value of the test statistic. O B. 27.9907 <2 <79.4900 OD, χ2<27.9907 F. χ2-79.4900 0 H. X2 < 30.4750 or 77.3860 2-35,28 (Round to four decimal places as needed.) c. Use the results, parts a and b, to make the appropriate conclusion. Choose the correct answer below 0 A. Reject Ho. There is insufficient evidence to indicate the O B. Reject Ho-There is sufficient evidence to indicate the variance is different from 100 at 0.01 variance is different from 100 at α-0.01 ° C. Do not reject Ho. There is insufficient evidence to 0 D. Do not reject Ho . There is sufficient evidence to indicate the variance is different from 100 at α-0.01 indicate the variance is different from 100 at α-0.01
