You have been asked to determine if two different production processes have different mean numbers of units produced per hour. Process 1 has a mean defined as and process 2 has a mean defined as 2. The null and alternative hypotheses are Ho: H1 H2 0 and H: H - >0. The process variances are unknown but assumed to be equal. Using random samples of 36 observations from process 1 and 49 observations from process 2, the sample means are 60 and 45 for populations 1 and 2 respectively. Complete parts a through d below.

Can you reject the null hypothesis, using a probability of Type I error = 0.05, if the sample standard deviation from process 1 is 29 and from process 2 is 25? The test statistic is t = (Round to three decimal places as needed.) Question Viewer
