Please answer B, C, & D. The average final exam score for the statistics course is 82%. A professor wants to see if the average finalexam score for students who are given colored pens on the first day of class is different. The final examscores for the 13 randomly selected students who were given the colored pens are shown below. Assumethat the distribution of the population is normal.99, 89, 68, 88, 75, 89, 85, 93, 83, 68, 84, 91, 81What can be concluded at the the a = 0.05 level of significance level of significance?a. For this study, we should use t-test for a population meanb. The null and alternative hypotheses would be:Но:?v Select an answer vHj: ?v| Select 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 isf. Based on this, we should fail to rejectthe null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the population mean is not significantly different from 82 at a = 0.05, sothere is statistically insignificant evidence to conclude that the population mean final examscore for students who are given colored pens at the beginning of class is equal to 82.The data suggest the populaton mean is significantly different from 82 at a = 0.05, 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 different from 82.O The data suggest that the population mean final exam score for students who are given coloredpens at the beginning of class is not significantly different from 82 at a = 0.05, 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 different from 82.%3D
