Answer:
39 (the first option listed among the possible answers)
Step-by-step explanation:
Recall that the mean is the same as the average of the numbers you have listed, that is the addition of all divided by the number of entries you use:
mean = [tex]\frac{29+42+45+39+36+41+38}{7} =\frac{270}{7} =38.57[/tex]
Therefore, rounding to the nearest integer, our answer s: 39
