The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s
e-lub [12.9K]

Using the normal distribution, we got that expression for the z-score of her test score is

z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1

<h3>What is Normal Probability Distribution?</h3>

it's a type of probability distribution which is  symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.

Given that mean =\mu=79

and standard deviation =\sigma = 7

X=73

we know that formula of z-score is

z=\frac{X-\mu}{\sigma}

Hence Z-score can be calculated as

z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1

Using the normal distribution, we got that expression for the z-score of her test score is

z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1
