For the first part of the problem using bootstrap, the critical level (alpha) needs to be determined from 1 minus the confidence level, which is 1-0.95, resulting in an alpha value of 0.05.

Step 1: Check assumptions and write hypotheses. The assumption here is that the sampling distribution is approximately normal. From the given StatKey output, the randomization distribution is approximately normal. \ (H_0\colon p=0.50\) \ (H_a\colon p>0.50\) 2. Calculate the test statistic.
