Before a strike prematurely ended the 1994 major league baseball season, Tony Gwynn of the San Diego Padres had 165 hits in 419 at bats, for a .394 batting average. There was discussion about whether Gwynn was a potential .400 hitter that year. This issue can be couched in terms of Gwynn's probability of getting a hit on a particular at bat, call it 6. Let Yi be the Bernoulli(0) indicator equal to unity if Gwynn gets a hit during his ith at bat, and zero otherwise. Then. Y1. Y2, Yn is a random sample from a Bernoulli(6) distribution, where 0 is the probability of success, and n = 419. Our best point estimate of 0 is Gwynn's batting average, which is just the proportion of successes: y̅ = .394. Using the fact that se(y̅) √y̅ (1- y̅) /n,.construct an approximate 95% confidence interval for 0. using the standard normal distribution. Would you say there is strong evidence against Gwynn's being a potential .400 hitter? Explain.
