Question:
a. One comparison of interest to the researchers is whether the mean creative use of ideas scale score for employees who report positive spillover of work skills to family life differs from the mean scale score for employees who did not report positive work spillover. Give the null and alternative hypotheses that will allow the researchers to make the comparison.

c. The results of the test are shown in the SPSS printout below. Interpret these results. Make the appropriate conclusion using α = .05.
d. A 95% confidence interval for the difference between the mean use of creative ideas scale scores is shown in the last column of the SPSS printout. Interpret this interval. Does the inference derived from the confidence interval agree with that from the hypothesis test?
e. The data also include the qualitative variable, Gender, for each worker. The researchers want to know whether the proportion of male workers in the two groups is significantly different. A Minitab printout of the analysis is shown below. Fully interpret the results in the words of the problem.
