Question

What is the mean of the following set of numbers (57, 90, 70, 68, 61, 62)?

A) 64
B) 65
C) 68
D) 72

Answer 1

The mean is,

C) 68

Explanation:

The mean is calculated using the formula,

`m = (sum \ of \ the \ terms)/(number \ of \ terms)\\`

Now, there are 6 terms (in this case numbers) so,

we have to divide by 6,

and sum them.

`m = (57+90+70+68+61+62)/6\\m=408/6\\\\m=68`

Hence the mean is 68
