- In 2003, Major League Baseball took steps to speed up the paly of baseball games and make games a more consistent duration. In a sample of 41 games in 2002, the average duration of a game was 2 hours and 58 minutes with a standard deviation of 38 minutes. A similar survey in 2003 of 31 games found that the average duration was 2 hours and 40 minutes with a standard deviation of 18 minutes. When testing the hypothesis (at the 10% level of significance) that the variance has been reduced, what is the critical value? (please round your answer to 2 decimal places) ***PLEASE SHOW WORK***

The lengths of major league baseball games are approximately normally distributed and average 2 hours and 50.1 minutes (170.1 minutes), with a population standard deviation of 18 minutes. It has been claimed that New York Yankee baseball games last, on the average, longer than the games of the other major league teams. To test the truth of this statement, a sample of eight Yankee games were randomly identified and the "time of the game" (in minutes) for each obtained. 199...

Major league baseball game durations are normally distributed with a mean of 150 minutes and a standard deviation of 35 minutes. What is the probability of a game duration of between 170 and 200 minutes? Please specify your answer in decimal terms and round your answer to the nearest hundredth

Attendance at minor league baseball games continues to increase. For the most recent year, the average attendance at a minor league baseball game was 3,530. Halfway through the current season, the league conducted a sample to see if attendance was greater than last year. A sample of 92 games showed an average attendance of 3,740 per game with a sample standard deviation of 810. At a confidence level of .01, what is your conclusion?

Suppose that a major league baseball game has an average length of 2.9 hours with a standard deviation of 0.5 hours. It is known that game length is not normally distributed. Suppose a random sample of 36 games is taken from the population. What is the approximate probability that average game length will be greater than 3.15 hours or less than 2.75 hours? Round to the nearest thousandth.

One season, the average little league baseball game averaged 2 hours and 46 minutes (166 minutes) to complete. Assume the length of games follows the normal distribution with a standard deviation of 10 minutes. What is the probability that a randomly selected game will be completed in more than 180 minutes? (Round to four decimal places as needed.)

In 2018 there were 2416 major League baseball games. The mean attendance was 28837 with a standard deviation of 10853. Let us assume that the attendance in any game is independent from the attendance in any other game. Suppose, we randomly select 289 games, with replacement, from the list of 2416 games and look at the attendance for each game selected. Let M be the random variable representing the mean attendance of the selected games. Let T = the random...
