Question
Do political sclence classes require more writing than history classes? The 57 randornly selected political
science classes assigned an average of 17.8 pages of essay writing for the course. The standard deviation
for these 57 classes was 4 pages. The 58 randomly selected history classes assigned an average of 16.8
pages of essay writing for the course. The standard devlation for these 58 classes was 5.6 pages. What can
be concluded at the a = 0.10 level of significance?
For this study, we should use Select an answer
a. The null and alternative hypotheses would be:
Ho: Select an answerv Select an answerv Select an answerv
H: Select an answerv Select an answerv Select an answerv
b. The test statistic ?v =
(please show your answer to 3 decimal places.)
c. The p-value =
d. The p-value is ?v a
e. Based on this, we should Select an answerv the null hypothesis.
f. Thus, the final conclusion is that ...
(Please show your answer to 4 decimal places.)
O 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 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.
O The results are statistically significant ata = 0.10, so there is sufficient evidence to conclude
that the mean number of required pages for the 57 political science classes that were observed
is more than the mean number of required pages for the 58 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.
