Stats To quality for a police academy, applicants are given a lest of physical Itness. Ihe scores are normallyDistributed with a

omeli [17]

Since we want just the top 20% applicants and the data is normally distributed, we can use a z-score table to check the z-score that gives this percentage.

The z-score table usually shows the percentage for the values below a certain z-score, but since the whole distribution accounts to 100%, we can do the following.

We want a z* such that:

$P(z>z^*)=0.20$

But, to use a value that is in a z-score table, we do the following:

$\begin{gathered} P(zz^*)=1 \\ P(zz^*)=1-0.20=0.80 \end{gathered}$

So, we want a z-score that give a percentage of 80% for the value below it.

Using the z-score table or a z-score calculator, we can see that:

$\begin{gathered} P(zNow that we have the z-score cutoff, we can convert it to the score cutoff by using:[tex]z=\frac{x-\mu}{\sigma}\Longrightarrow x=z\sigma+\mu$

Where z is the z-score we have, μ is the mean and σ is the standard deviation, so:
