The Hawk-Eye electronic system is used in tennis for displaying an instant replay that shows whether a ball is In or Out. In the first U. S. Tennis Open that used the Hawk-Eye System, players could challenge calls made by the line judges. The Hawk-Eye system was then used to confirm or overturn the line judge’s call. Players made 836 challenges and 332 of those challenges were successful with the call overturned. Interest centers on testing the claim that the proportion of challenges that are successful is greater than 40%. What is the correct p-value based on the data observed?
