You are out for the evening, and you overhear someone say that the 1985 Kansas City Royals were better than the 2015 Kansas City Royals. Can this be tested using two-sample hypothesis testing? Explain why or why not. Assume that it could be done: how would you do it?

Solutions

Expert Solution

  • We need to identify the stats that can define which is better.
  • Have a sample data for both sets

Define a hypothesis that mu of 85 > mu 15

Then calculate the t statistics and the p value.

So we check the degrees of freedom etc.

So, we check if the t value is significant accordingly the hypothesis is accepted or rejected.

If Rejected means 85 was not better than 15.
