The average final exam score for the statistics course is 74%. A professor wants to see if the average finalexam score for students who are given colored pens on the first day of class is lower. The final exam scoresfor the 11 randomly selected students who were given the colored pens are shown below. Assume that thedistribution of the population is normal.76, 78, 77, 67, 63, 79, 50, 63, 70, 63, 66What can be concluded at the the a = 0.01 level of significance level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ?v Select an answerHj: ? vSelect an answer vc. The test statistic ? v(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is ? vaf. Based on this, we should Select an answer|the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the populaton mean is significantly lower than 74 at a = 0.01, so there isstatistically significant evidence to conclude that the population mean final exam score forstudents who are given colored pens at the beginning of class is lower than 74.O The data suggest the population mean is not significantly lower than 74 at a = 0.01, so thereis statistically insignificant evidence to conclude that the population mean final exam score forstudents who are given colored pens at the beginning of class is equal to 74.O The data suggest that the population mean final exam score for students who are givencolored pens at the beginning of class is not significantly lower than 74 at a = 0.01, so there isstatistically insignificant evidence to conclude that the population mean final exam score forstudents who are given colored pens at the beginning of class is lower than 74.
