5. One sample has a M=6 and the second has a mean of M=12. The two samples are combined into a single set of scores. (1.5 points) a. What is the mean for the combined set if both of the original samples have n=4? M1 = 6 1= M= 2x1+ 2X2 24+48 9 N 1: 4 4+4 2 x = 24 b. What is the mean for the combined set if the first sample has n=3 and the second sample has n=6 c. What is the mean for the combined set if the first sample has n=6 and the second sample has n=3 6.
