Question

The z-test Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests, a sample is selected from a normal population distribution with a mean of H 30 and a standard deviation of ơ 8. After the treatment is administered to the individuals in the sample, the sample mean if found to be M 33. In each case use a two-tailed test with 05 a. For the first test, assume that the sample consists of n 16 individuals. b. For the second test, assume that the sample consists of n 64 individuals. c. Explain in your own words how the outcome of the hypothesis test is influenced by the sample size Note: Be sure and show a full diagram of the research design. Also show all steps and calculations you made for each test following the process outlined in the z-test formula sheet handout. What statistical decision do you make in each case? Finally report your results professionally in APA format (see last step of the formula sheet for this module)

Please this is the second time am posting this particular question, reason being that I could not see what the other tutor wrote. please make your writing bold Thanks
