For the first half of a baseball season, a player had 85 hits out of 270 times at bat. The player's batting average was 85 270 ≈ 0.315. During the second half of the season, the player had 56 hits out of 275 times at bat. The player's batting average was 56 275 ≈ 0.204.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
For the first half of a baseball season, a player had 85 hits out of 270 times at bat. The player's batting average was
| 85 |
| 270 |
During the second half of the season, the player had 56 hits out of 275 times at bat. The player's batting average was
| 56 |
| 275 |
(Round your answers to three decimal places.)
(b) What is the player's batting average for the complete season?
(c) Does the answer in part (a) equal the average in part (b)?
