Examine the statistical choices under €œanalyze€ in SPSS. Click on compare means. To compare an observed mean to some benchmark or hypothesized population mean, the available choice is a one-sample t-test. A researcher is preparing a report and finds the following result testing a hypothesis that suggested the sample mean did not equal 14:
a. What is the p-value? Is the hypothesis supported?
b. Write the 95% confidence interval which corresponds to an α of 0.05.
c. Technically, since the sample size is greater than 30, a Z-test might be more appropriate. However, since the t-test result is readily available with SPSS, the research presents this result. Is there an ethical problem in using the one-samplet-test?
