Do political science classes require more writing than history classes? The 55 randomly selected political
science classes assigned an average of 16.9 pages of essay writing for the course. The standard deviation for
these 55 classes was 3.8 pages. The 44 randomly selected history classes assigned an average of 14.8 pages of
essay writing for the course. The standard deviation for these 44 classes was 4.6 pages. What can be
concluded at the a = 0.10 level of significance?
For this study, we should use

d. The p-value is ? a
e. Based on this, we should Select an answer O the null hypothesis.
f. Thus, the final conclusion is that ...
The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude
that the population mean number of pages of writing that political science classes require is more
than the population mean number of pages of writing that history classes require.
O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude
that the mean number of required pages for the 55 political science classes that were observed is
more than the mean number of required pages for the 44 history classes that were observed.
O The results are statistically insignificant at a = 0.10, so there is insufficient evidence to conclude
that the population mean number of pages of writing that political science classes require is more
than the population mean number of pages of writing that history classes require.
O The results are statistically insignificant at a = 0.10, 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.
