Many say that baseball, which is commonly called America's National pastime, is a game with a low success rate. Consider
Mookie Betts, one of the greatest players the sport has ever seen. He had a batting average (BA) of .346 during the 2018 season.
His batting average was the highest of all players for that year.
A player's batting average is computed by dividing the number of times a player has a hit by the player's total number of at-bats.
BA=
Number of Hits
Number of At-Bats
Notice that this formula looks a lot like a probability where the sample space is the set of all at-bats and the event is getting a hit.
When fans talk about batting averages, they commonly think of it in terms of probability. That is, if a player is batting .250, then
there is a 25% chance that they will get a hit at their next at-bat.
1. Do you agree with the interpretation of the batting average as a probability? Is it possible to compute the theoretical
probability that a player will get a hit when at bat?…
It is costly in both time and money to go to college. Does it pay off? According to the Bureau of the Census, the answer is yes. The average annual income (in thousands of dollars) of a household headed by a person with the stated education level is as follows: 24.5 if ninth grade is the highest level achieved, 41.4 for high school graduates, 59.1 for those holding associate degrees, 82.2 for those with bachelor's degrees, 100.6 for those with master's degrees, and 121.9 for those with doctoral degrees. Make a bar graph showing household income for each education level.
