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 v Select an answer ♥ (Please ențer a decimal)
b. The test statistic ? ♥ =
(please show your answer to 3 decimal places.)
c. The p-value =
(Please show your answer to 4 decimal places.)
d. The p-value is ? ♥ a
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 significant at a = 0.05, so there is sufficient evidence to
conclude that the population mean test score taking the exam alone is greater than 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 higher on average taking the exam alone
compared to the classroom setting.
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 insignificant at a = 0.05, so there is insufficient evidence to
conclude that the population mean test score taking the exam alone is greater than the
population mean test score taking the exam in a classroom setting.

Do students perform better when they take an exam alone than 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.
