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 15 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 75, 9o, 39, 76, 100, 95, 87, 88, 95, 73, 85, 75, 77, 71, 78 What can be concluded at the the a = 0.01 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: :1 l: 0 Ho: ? G Select an answer :2 H1: ? G Select an answer 6 c. The test statistic ? o = I: (please show your answer to 3 decimal places.) cl. The p-value = [: (Please show your answer to 4 decimal places.) e. The p-value is ? c a f. Based on this, we should Select an answer c the null hypothesis. g. Thus, the final conclusion is that O The data suggest that the population mean final exam score for students who are given colored pens at the beginning of class is not significantly higher than 81 at oz = 0.01, so there is statistically insignificant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is higher than 81. O The data suggest the population mean is not significantly higher than 81 at o: = 0.01, so there is statistically insignificant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is equal to 81. O The data suggest the populaton mean is significantly higher than 81 at 07 = 0.01, so there is statistically significant evidence to conclude that the population mean final exam score for students who are given colored pens at the beginning of class is higher than 81
