5. In 2006, tenis introduced a challenge system in which a player can challenge a decision as to
whether a tennis ball was correctly called 'in’ or ´ouť by an official. In the 2015 U.S. Open Tennis
Championship there were a total of 850 player challenges between both the Men's and Women's
Singles matches. These challenges were determined either to be correct (meaning the player was

was correct). These 850 challenges are summarized in the table below.

(a) Calculate the proportion of all challenges that were determined to be correct.
(b) Using these data as a representative sample of all player challenges in professional tennis, a 95%
confidence interval for the difference in the proportion of men's and women's challenges that are
determined to be correct (men – women) was found to be 0.04 ± 0.06. All conditions for
inference were met. Does this confidence interval provide convincing statistical evidence that
there is a difference in the effectiveness with which men and women use the challenge system?

A scientific study has demonstrated that the best time for a player to use a challenge is when the
tennis ball was called 'out' but the player believes that the ball was actually ʻin’ because when objects
travel faster than the human eye the umpire is left to fill the gap with their own perception. The table
below shows the Women's Singles challenges based on if the tennis ball was called ´out’ or 'in.

(d) Using these data as a representative sample of all player challenges in professional tennis, a 95%
confidence interval for the difference in the proportion of correct challenges when the umpire

All conditions for inference were met. Does this confidence interval provide statistical evidence
