I am asking for help on the second set of three bullet points starting with "Find the test statistic..." and ending with "Explain what the p-value represents."

Here is the scenario and pertinent data: 

A researcher wants to examine whether encouraging students to write about their thought processes affect 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. Here are the results of the survey:

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?

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.
