Question 1
The average final exam score for the statistics course is 79%. 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 lower. The final exam scores for
the 14 randomly selected students who were given the colored pens are shown below. Assume that the
distribution of the population is normal.
75, 51, 62, 89, 53, 77, 58, 64, 58, 73, 91, 62, 57, 51
What can be concluded at the the a = 0.10 level of significance level of significance?
