Question

How do you use the z-score to determine `P(0<z<0.94)`?

Answer 1

`P(0 < Z< 0.94)=0.3264`

Explanation:

`P(0 < Z< 0.94)=P(Z < 0.94)-P(Z<0)`

from tables we have

`P(0 < Z< 0.94)=0.8264-0.5`

`P(0 < Z< 0.94)=0.3264`

Answer 2

Here's another way to do it.

Explanation:

Use the normal cumulative distribution function on your graphing calculator.

You're trying to find the probability of getting a value in between `0` and `0.94`, and for a `z`-score distribution, the mean is `0` and the standard deviation is `1`. Enter these numbers into your calculator:

`"normalcdf" (0, 0.94, 0, 1) ~~ 0.3264`
