Do political science classes require less writing than history classes? The 47 randomly selected political science classes assigned an average of 19 pages of essay writing for the course. The standard deviation for these 47 classes was 5.6 pages. The 56 randomly selected history classes assigned an average of 21.9 pages of essay writing for the course. The standard deviation for these 56 classes was 4.1 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 answer Select an answer Select an answer v H: Select an answer v Select an answer v Select an answer v b. The test statistic ? v (please show your answer to 3 decimal places.) c. The p-value = 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... (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 less 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 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 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 at a = 0.10, so there is sufficient evidence to conclude that the mean number of required pages for the 47 political science classes that were observed is less than the mean number of required pages for the 56 history classes that were observed.

Transcribed Image Text:Do political science classes require less writing than history classes? The 47 randomly selected political
science classes assigned an average of 19 pages of essay writing for the course. The standard deviation for
these 47 classes was 5.6 pages. The 56 randomly selected history classes assigned an average of 21.9 pages
of essay writing for the course. The standard deviation for these 56 classes was 4.1 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 answer v
Select an answer v
Select an answer v
H: Select an answer v
Select an answer v
Select an answer v
b. The test statistic ? v =
(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 ? va
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 = 0.10, so there is sufficient 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 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 less 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 at a = 0.10, so there is sufficient evidence to conclude
that the mean number of required pages for the 47 political science classes that were observed
is less than the mean number of required pages for the 56 history classes that were observed.
