Question

If the formula pictured below is used to find the mean of the following sample, what is the value of N?

Answer 1

Choice D). 8

Explanation:

The value on n is simply the number of values or the size of the sample data. In our case, we have a total of 8 data values. The value of n will thus be 8

Answer 2

Choice D is correct answer.

Explanation:

We have given a list of values.

2,63,88,10,72,99,38,19

We have to find mean and value of n.

n is the total number of values.

Hence, n = 8

Formula to find mean is :

Mean = sum of values / number of values

Sum of values = 2+63+88+10+72+99+38+19 = 391

Number of values = 8

Mean = 391/8

Mean = 48.875

Mean of the following sample is 48.875
