(This example was introduced in Chapter 5.) How many base hits can a baseball team expect to get in a game? Frohlich (1994) recorded the number of hits by the 28 Major League Baseball teams for all of the games played in 1989 to 1993 (each team plays 162 games a year). He found that the number of hits the teams made in the games was normally distributed, with a mean of 8.72 and a standard deviation of 1.10. What...

What is the probability that someone consumes exactly 15 gallons of water? b. What is the probability that someone consumed between 30 and 40 gallons of water? c. 99.5% of people consumed less than how many gallons of water?
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.
