Response rates for customer complaints by Companies A and B are observed for 8 consecutive days and are given below. Although they have similar response rates on average, one claim is that they are not equally consistent in responding to customer complaints. Assuming that both populations are Normal, check this claim by testing the hypothesis that o, =6, against the alternative that o, #6, at a = 0.05 significance level and by using the p-value approach. 0.47 0.41 0.41 0.53 0.38 0.48 0.53 0.54 (A) 0.38 0.38 0.39 0.41 0.38 0.38 0.39 0.39 (B) (a) The f value for the test can be computed as (Round to two decimal places including any zeros.) (b) The p-value is the total tail probability corresponding to the calculated test value, which is then compared to a. In a two-tailed test, this is 2P(F>f) or, in a right-tailed test, this is P(F>f). The p-value for the test can be calculated as (Round to four decimal places including any zeros.) (c) V the null hypothesis because there is evidence that o, 02.
