A professional tennis player claims to get 90% of her second serves in. In a recent match, the player missed 5 of her first 20 second serves. Is this a surprising result if the player's claim is true? Assume that the player has a 0.10 probability of missing each second serve. We want to carry out a simulation to estimate the probability that she would miss 5 or more of her first 20 second serves. The dotplot displays the number of second serves missed by the player out of the first 20 second serves in 100 simulated matches. ………………………… ******** ****** 3 4 5 6 1 2 Number of missed serves in simulated match Is there convincing evidence that the player misses more than 10% of her second serves? Why or why not? No, there is not convincing evidence that the player misses more than 10% of her second serves. Missing 5 out of 20 is better than expected. No, there is not convincing evidence that the player misses more than 10% of her second serves. Assuming the player makes 90% of her second serves, there is only a 7% chance that she would miss 5 or more of her first 20 second serves. No, the player could have just had a particularly unlucky streak. There is no way to determine the answer to this if we don't know how many times the player will serve overall during a tennis match. Yes, because 10% of 20 is 2 and most of the points on the dotplot fall at 2 or higher. This is evidence that the player misses more than 10% of her second serves.
