I am asking for help on the first three bullet points to the following scenario.

A researcher wants to examine whether encouraging students to write about their thought processes affects student confidence level with mathematical processes. They survey 150 students who have recently completed 2 math courses, one which has written assignments and one which does not, asking whether they are or are not confident with mathematical processes. The results of the survey are as follows:

Written            Confident   Not Confident Total

Assignments?

No                   41               35                   76

Yes                 53               21                    74

Total               94               56                    150

Does the evidence suggest a relationship between written assignments and confidence with mathematical processes? 

 

- For each of the five scenarios that follow, do the following steps in the hypothesis testing process, with the level of significance a = .05 for each. . State the null and alternative hypotheses, explaining your thought process. State which type of test you will do, of the five tests introduced in this week's interactive reading assignments, and how you know. • State whether the area you will be interested in, when doing the test, will be to the left, to the right, or both, and how you know. . Find the test statistic for the test you determined was appropriate. . Find the p-value corresponding to the test statistic, given the direction you determined for the area. Explain what the p-value represents. State whether the results are or are not statistically significant, explaining in terms of the relationship between the p-value and a Explain what the results of the test mean, using the vocabulary of hypothesis testing. Explain what the results of the test mean, using words other than the vocabulary of hypothesis testing. • Answer any other questions which accompany the scenario. 1 O 0 O researcher wants to examine whether encouraging students to write about their thought processes affects student confidence level with mathematical proce recently completed two math and one which does not. asking whether they are or are not confident with mathematical processes.
