Answer:
The mean of the samples is 21
Step-by-step explanation:
Mean is defined as the average sum of numbers i.e total sum of given numbers divided by the total number.
Given the randomly selected numbers as shown;
7, 100, 1, 3, 7, 10, 15, 12, 17, 38
Total sum of numbers = 7+ 100 + 1 + 3 + 7 + 10 + 15 + 12 + 17 + 38
= 210
Total numbers given = 10
Mean = 210/10
Mean = 21
