A. Using the five steps from the online notes, conduct a randomization test given that 9 students in a random sample of 15 use the eTextbook. Be sure to include your relevant StatKey output. [25 points]

Step 1: Determine what type of test you need to conduct and write the hypotheses.

Step 2: Use StatKey to construct a randomization distribution under the assumption that the null hypothesis is true. Take at least 5000 resamples.

Step 3: Use the randomization distribution to find the p-value. Include a screenshot of your distribution with the p value in red and make a statement identifying your p value

Step 4: Decide if you should reject or fail to reject the null hypothesis.

Step 5: State a real-world conclusion in relation to the original research question.
