Estimating the combined mean values for the given data.

One sample of n = 4 scores has a mean of M = 10, and a second sample of n = 8 scores has a mean of M = 20. If the two samples are combined, the mean for the combined sample will be

1. Equal to 15

2. Greater than 15 but less than 20

3. Less than 15 but more than 10

4. None of the other choices is correct
