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 81 79 77 83 82 66 71 91 Classroom 73 77 73 73 81 53 70 84 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: Но: рd Select an answer v|0 vV (please enter a decimal) H1: ud Select an answer v|0 vv (Please enter a decimal) b. The test statistic t v (please show your answer to 3 decimal places.) లో c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is svV a e. Based on this, we should reject 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. 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 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 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.

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:
Но: рd
Select an answer v0
vV (please enter a decimal)
H1: ud
Select an answer v
Vv (Please enter a decimal)
b. The test statistic t v
(please show your answer to 3 decimal places.)
లో
c. The p-value =
(Please show your answer to 4 decimal places.)
d. The p-value is svV a
e. Based on this, we should reject
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.
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 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 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.
