Maxforce, Inc., manufactures racquetball racquets by two different manufacturing processes (A and B). Because the management of this company is interested in estimating the difference between the average time it takes each process to produce a racquet, they selected independent samples from each process. The results of the samples and the population variances are shown below. Process A Sample Size 30 Sample Mean (in minutes) 43 Population Variance 64 Test the following hypotheses. Ho: HAMB Ha: HAMB a. Calculate the value of the test statistic. (Round to two decimal places) b. What is the p-value? (Round to four decimal places) c. At a 5% significance level, the decision is to Process B 35 48 70 10
