Instead of using a 1-sample z test, the student performed a simulation to estimate the sampling distribution of the proportion of swimmers who would swim faster with the polyurethane suit. To do this, he flipped a fair coin 8 times and recorded the proportion of heads. Then he repeated this process 50 times. The results of 50 sets of 8 flips are shown in the dotplot below. Use the results of the simulation to estimate the p-value for a test of the hypotheses stated in part (c). Explain how you obtained your estimate.
