Textbook Problem

One sample has a mean of *M* = 5 and a second sample has a mean of *M* = 10. The two samples are combined into a single set of scores.

**a.**What is the mean for the combined set if both of the original samples have*n*= 5 scores?**b.**What is the mean for the combined set if the first sample has*n*= 4 scores and the second sample has*n*= 6?**c.**What is the mean for the combined set if the first sample has*n*= 6 scores and the second sample has*n =*4?

**a.**

To determine
