QUESTION:

Problem  18BSC

In Exercise, test the given claim.

Baseball Player Births In his book Outliers, author Malcolm Gladwell argues that more American-born baseball players have birthdates in the months immediately following July 31 because that was the cutoff date for nonschool baseball leagues. The table below lists months of births for a sample of American-born baseball players and foreign-born baseball players. Using a 0.05 significance level, is there sufficient evidence to warrant rejection of the claim that months of births of baseball players are independent of whether they are born in America? Do the data appear to support Gladwell’s claim?

ANSWER:

Solution  18BSC

Step 1 of 1

We are given a data set of American born players and non-American born players, and month of birth. We have to test the claim that months of birth of players are independent of whether they are born in America.

Step 1: To test the claim we need to fulfil certain assumptions.

1. We assume that the sample has been randomly selected because of the structure of the study.

2. The results are tabulated as frequencies.

3. The expected frequencies are more than five in every column.
