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
