Question

AEV

Suppose "true-talent" (stable given an infinitely large sample) average exit velocity (AEV) on batted balls for all players is normally distributed with a mean of 87 mph and a standard deviation of 2.5 mph.

 

For any sample of individual batted balls hit by one player, the standard deviation of exit velocity of those batted balls around this particular player's true-talent AEV is 9 mph.

 

At this point in the season, Marco Masher has a total of 10 batted balls with an average exit velocity of 96 mph. Given only this information, the best estimate for his "true talent" exit velocity is closest to which whole number?

    A previous study of professional baseball players showed that the standard deviation of home runs hit by players who play a full season was 7.23 homeruns. If researchers want to conduct a new study to determine the number of homeruns a player hits in a year, how many players would they need in their study if they want to be within 1.5 home runs of the true mean? Use a 95% level of confidence?

Assume that we want to test the hypothesis that the average weight of the population of all players is 225 lbs, against the alternative hypothesis that the average weight is less that 225 lbs. Assume also that the population standard deviation of player weights is 26 lbs. Let the probability of making a type I error (a) be 0.05. What size random sample would be necessary if we want the probability of...

    Suppose that over the past 30 years during any given week of the major-league season, an average of µ = 12 players are hit by wild pitches. Assume that the distribution is normal with a standard deviation of σ =3. For a sample of n = 4 weeks, in which the daily temperature was extremely hot, the weekly average of hit-by- pitch players was M = 15.5. Are players more likely to get hit by pitches during hot weeks? Use...

In baseball, his predicted RPG (runs per game) statistics considers the entire player's offensive statistics and is claimed to be the best measure of a player's true offensive value. A set of sample data was collected for RPG and a variety of offensive statistics for a recent Major League Baseball (MLB) season for members of the New York Yankees. The variables are...
