Question

What is the z-value for X = 24 in a set of normally distributed data with u = 20 and 0 = 1.6?z-value =

Answer 1

2.5

Step-by-step explanation:

The z-value for a normally distributed data is calculated using the formula below:

`Z=(X-\mu)/(\sigma)`

Substitute the given values:

`\begin{gathered} Z=(24-20)/(1.6) \\ =(4)/(1.6) \\ =2.5 \end{gathered}`

The z-value is 2.5
