Please use the following information to answer questions 5d-5e: To evaluate the effect of a treatment, a sample of n = 8 is obtained from a population with a mean of µ = 40, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be x̅ = 35. If the sample variance is s2 = 72, are the data sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with α = .05. 5d. Based on the calculated test statistic, would you reject the null hypothesis established in question 5a (MUST SHOW WORK FOR THIS PROBLEM)? Group of answer choices a. yes b. no 5e. Based on the previously conducted steps, can it be concluded that the treatment had a significant effect (MUST SHOW WORK FOR THIS PROBLEM)?

A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled, and the average error from the industry standard is measured in millimeters. The results are presented here. Process A Process B Sample mean 2.0 3.0 Standard deviation 1.0 0.5 Sample size 12 14 The researcher is interested in determining whether there is evidence that the two processes yield different average errors. The population standard deviations are unknown but are assumed equal. This example is what type of test? Multiple Choice A one-sample test of means A two-sample test of means A paired t-test A test of proportions
