Problem 1 - Hypothesis Testing: The two-sample case (worth 5.5 points) Be sure to show all of the steps and the details of your calculations.

Is there a statistically significant difference between males and females in terms of the number of hours they spend reading newspapers in a typical week? The mean number of hours per week (by gender) that respondents reported reading a daily newspaper is shown below. Data has been obtained from a nationally random sample. Complete the five-step model and a short interpretation of your results. You are free to choose any alpha in step 3 but you should limit your choice to one of the common alphas that are used in social research; indicate the corresponding critical region.
