Question

A set of data with a mean of 62 and a standard deviation of 5.7 is normally distributed. Find the value that is +3 standard deviations from the mean.

Answer 1

79.1

Explanation:

Given that :

Mean, μ = 62

Standard deviation, σ = 5.7

The value, x that is +3 standard deviations from the mean :

x = μ + 3(σ)

x = 62 + 3(5.7)

x = 62 + 17.1

x = 79.1
