Answer:
The mean for the combined sample = 6.
Step-by-step explanation:
We have been given that one sample of n = 10 scores has a mean of M = 8.
So the sum of 10 scores for 1st sample will be:
We are also told that second sample of n = 5 scores has a mean of M = 2.
So the sum of 5 scores for 2nd sample will be:
When the both samples are combined, so total points will be: and total scores will be .
Therefore, the mean for the combined sample will be 6.
All you have to do is put 36/125. This will get you .288. When rounded to the nearest percent, it is 28%.
