. Question 15 v A random sample of hourly wages (in S} of 33 workers at a Large company yields a variance of 8.28. At a = 0.05, test the claim that the variance of hourly wages [in S) at the company is at least 10.08. 1. The null hypothesis is Ho: {112-52 .3 10.08 "iii- 52 '3 10.08 C' s 2 10.08 {:21- 0- '3 10.08 2. This is a '33:? right' left? two tailed test with d.f. = 3a. The STS [to 2 decimals] is X2 = 3b. The P-value {to 3 decimals} is: 4a. At or = 0.05, the decision is: '33:? Accept Ha '3' Reject Ho 0 Do not reject Ho '3' Accept Ho 4b.
