Question

2.  In this question set you will be using StatKey to conduct randomization tests for a

single proportion. A STAT 200 instructor wants to know if less than half of online students regularly use the Canvas app ( > 5 times a week).[70 points total]

 

A. Using the five steps from the online notes, conduct a randomization test given that 6 students in a random sample of 15 use the Canvas app on a regular basis (> 5 times a week). Be sure to include your relevant StatKey output. [30 points]

 

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

 

Step 2: 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.

 

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.

 

 

B. Using the five steps from the online notes, conduct a randomization test given that 48 students in a random sample of 120 use the Canvas app regularly. Be sure to include your relevant StatKey output. [30 points]

 

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

 

Step 2: 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.

 

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.

 

 

C. In parts A and B the hypotheses and sample proportions were the same. Explain why the p-value decreased when the sample size increased. [10 points]
