answer the following

This Question: 1 pt 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 p2. The null and alternative hypotheses are Ho: H1 - 12 50 and H1: H -#2 >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 46 for populations 1 and 2 respectively. Complete parts a through d below. Click the icon to view a table of critical values for the Student's t-distribution. a. Can you reject the null hypothesis, using a probability of Type I error o = 0.05, if the sample standard deviation from process 1 is 31 and from process 2 is 26? The test statistic is t= . (Round to three decimal places as needed.) The critical value(s) is(are) (Round to three decimal places as needed. Use a comma to separate answers as needed.) Since the test statistic is b. Can you reject the null hypothesis, using a probability of Type I error o = 0.05, if the sample standard deviation from process 1 is 23 and from process 2 is 33? The test statistic is t= (Round to three decimal places as needed.) The critical value(s) is(are) . (Round to three decimal places as needed. Use a comma to separate answers as needed.) Since the test statistic is c. Can you reject the null hypothesis, using a probability of Type I error o = 0.05, if the sample standard deviation from process 1 is 30 and from process 2 is 35? The test statistic is t= (Round to three decimal places as needed.) Enter your answer in each of the answer boxes
