Answer:

Step-by-step explanation:

The sample mean is given by dividing the standard deviation by the squareroot of SRS

Given standard deviation of 35 and SRS of 49, we know that the squareroot of 49 is 7 ie √49=7

By substituting the given values we can obtain the sample mean as follows.

sample mean=35/√49=35/7=5

The sample mean for the given question is hence 5
