A set of data items is normally distributed with a mean of 240 and a standard deviation of 32. Convert 272 to a? z-score

z-score = 1

Step-by-step explanation:

Given

Mean = μ=240

SD = σ=32

In order to find the z-score of a value, the mean is subtracted from the value and then divided by standard deviation.

The formula for z-score is:

z-score = (x-μ) / σ

Here x is the value whose z-score is to be found.

In the given question, x = 272

So,

z-score = (272-240) / 32

=32/32

=1

So, the z-score for 272 is 1 ...
