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

Answer:

2.5

Explanation:

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

$Z=\frac{X-\mu}{\sigma}$

Substitute the given values:

$\begin{gathered} Z=\frac{24-20}{1.6} \\ =\frac{4}{1.6} \\ =2.5 \end{gathered}$

The z-value is 2.5
