schepotkina [342]

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: 10\times 8=80

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: 5\times 2=10

When the both samples are combined, so total points will be: 80+10=90 and total scores will be 10+5=15.

\text {Mean for the combined sample}=\frac{\text{Total points of both data sets}}{\text{Total scores of both data sets}}

\text {Mean for the combined sample}=\frac{90}{15}

\text {Mean for the combined sample}=6

Therefore, the mean for the combined sample will be 6.
