Do political science classes require less writing than history classes? The 41 randomly selected political science
classes assigned an average of 18 pages of essay writing for the course. The standard deviation for these 41
classes was 3.1 pages. The 50 randomly selected history classes assigned an average of 20.1 pages of essay
writing for the course. The standard deviation for these 50 classes was 6 pages. What can be concluded at the
a = 0.01 level of significance?
For this study, we should use Select an answer
a. The null and alternative hypotheses would be:
Ho: Select an answer
H₁: Select an answer
Select an answer
Select an answer
b. The test statistic? =

e. Based on this, we should Select an answer the null hypothesis.
f. Thus, the final conclusion is that ...
(Please show your answer to 4 decimal places.)
O The results are statistically insignificant at a = 0.01, so there is statistically significant evidence
to conclude that the population mean number of pages of writing that political science classes
require is equal to the population mean number of pages of writing that history classes require.
O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to conclude
that the population mean number of pages of writing that political science classes require is less
than the population mean number of pages of writing that history classes require.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude
that the mean number of required pages for the 41 political science classes that were observed is
less than the mean number of required pages for the 50 history classes that were observed.
