A. 16
B. 13
C. 14
D. 15

Answer 1

The value of n in the formula x=1/n Σ xᵢ for finding the mean of a sample is 14.

Step-by-step explanation:

The formula x=1/n Σ xᵢ is used to find the mean of a sample, where n is the size of the sample, and Σ xᵢ represents the sum of all data points in the sample.

In this case, we have the sample {143, 36, 93, 2, 28, 83, 10, 22, 9, 84, 41, 3, 13, 20} and we need to find the value of n. By counting the number of data points in the sample, we find that there are 14 values. Therefore, the value of n is 14.
