James is a baseball player who hits left handed. Based on his past statistics, his strikeout rate against left-handed pitchers is 12.5%. He would like to reduce this rate, so he changes his batting stance. To test whether it works, he uses a pitching machine to simulate 200 at bats. In these, he struck out 16 times. James conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of strikeouts against left-handed pitchers using James's new stance is less than 12.5%.
