Question

The GPA at the BEST UNIVERSITY has a normal distribution with a mean 2.46 and standard deviation 1.13. Approximately what percent of the BEST UNIVERSITY students have their GPA below 1.54.

Answer 1

20.8%

Explanation:

Given:

μ = 2.46

τ = 1.13

x = 1.54

`\boxed{Z=(x-\mu)/(\tau)}`

`Z=(1.54-2.46)/(1.13)`

`= -0.814`

P(Z < -0.814) = 0.208

= 20.8%
