A sample of n = 10 and has mean of M = 5. If each score is multiplied by 3, then the new mean is?

The new mean of the sample is 15

Step-by-step explanation:

Given;

number of sample, n =10

initial mean of the sample, M = 5

initial total score of the sample = 5 x 10 = 50

If each score is multiplied by 3, the new score = 3 x 50 = 150

The new mean = new score / number of sample

The new mean = 150 / 10

The new mean = 15

Therefore, the new mean of the sample is 15
