Do students perform the same when they take an exam alone as when they take an exam in a classroom setting? Eight students were given two tests of equal difficulty. They took one test in a solitary room and they took the other in a room filled with other students. The results are shown below. Exam Scores Alone 86 86 65 73 91 74 90 91 Classroom 81 74 62 65 88 66 88 82 Assume a Normal distribution. What can be concluded at the the a - 0.05 level of significance level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer Select an answer Select an answer v (please enter a decimal) H: Select an answer v Select an answer Select an answer v (Please enter a decimal) b. The test statistic ? (please show your answer to 3 decímal places.) (Please show your answer to 4 decimal places.) c. The p-value - d. The p-value is inull hypothesis.

The test statistic (please show your answer to 3 decímal places.) (Please show your answer to 4 decimal places.) c. The p-value- d. The p-value e. Based on this, we should Select an answer v the null hypothesis. f. Thus, the final conclusion is that O The results are statistically insignificant at a 0.05. so there is statistically significant evidence to conclude that the population mean test score taking the exam alone is equal to the population mean test score taking the exam in a classroom setting. f. Thus, the final conclusion is that ... O The results are statistically insignificant at a - 0.05, so there is statistically significant evidence to conclude that the population mean test score taking the exam alone is equal to the population mean test score taking the exam in a classroom setting. O The results are statistically significant at a - 0.05, so there is sufficient evidence to conclude that the eight students scored the same on average taking the exam alone compared to the classroom setting. O The results are statistically significant at a - 0.05, so there is sufficient evidence to conclude that the population mean test score taking the exam alone is not the same as the population mean test score taking the exam in a classroom setting. O The results are statistically insignificant at a- 0.05, so there is insufficient evidence to conclude that the population mean test score taking the exam alone is not the same as the population mean test score taking the exam in a classroom setting.
