A semi-retired economist is thinking about retiring fully, and he finds himself checking his mutual fund portfolio daily to see how his investments are doing. He notices that the time it takes to log on to his investment account online varies widely, and he wonders whether the connection times vary by time of day. He decides to keep track of a random sample of connection times (in seconds), for five time periods: early morning, mid-day, early afternoon, late afternoon, and evening. Check whether the conditions required for one-way ANOVA are met. If they are, conduct a test of hypothesis at the 5% level of significance to determine whether the mean connection times are equal.
