Do political science classes require more writing than history classes? The 54 randomly selected political science classes assigned an average of 18.6 pages of essay writing for the course. The standard deviation for these 54 classes was 3.8 pages. The 46 randomly selected history classes assigned an average of 16 pages of essay writing for the course. The standard deviation for these 46 classes was 4.3 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 Select an answer v Select an answer v H1: 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 ? v a e. Based on this, we should |Select an answer v the null hypothesis. f. Thus, the final conclusion is that ... 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 54 political science classes that were observed is more than the mean number of required pages for the 46 history classes that were observed. The results are statistically significant at a = 0.01, 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. The results are statistically insignificant at o = 0.01, 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 = 0.01, 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
