The average final exam score for the statistics course is 81%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 16 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 81, 81, 96, 78, 92, 94, 87, 92, 75, 87, 69, 98, 68, 95, 98, 92 What can be concluded at the the a = 0.05 level of significance level of significance? a.
