l l) A study conducted by the Research Institute of America has concluded that the average number of hours inmates at state correctional facilities spend in their cells during a day is 19. You surveyed a sample of 10 state correctional facilities and found that the mean number of hours inmates spend in their cells during the day is 16. Conduct a statistical test to assess whether the mean number of hours inmates spend in their cells during the day from your sample (16 hours) differs from the mean number of hours inmates spend in their cells as reported by the Research Institute of America (19 hours) using the steps listed below: a) State your null and research hypotheses b) Indicate the appropriate statistical test c) With the signicance level set at .0], specify your critical region or value d) Compute the test statistic and report the obtained value e) Declare your decision (i.e., whether to reject or retain the nullhypothesis) t) Explain your decision in (e) above
