Question

suppose the z-score of your grade in this statistics course turns out to be .97. interpret this z-score.

Answer 1

A z score of 0.97 corresponds with a probability of 83.40%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation$

From the normal distribution table:

P(z < 0.97) = 0.8340 = 83.40%

A z score of 0.97 corresponds with a probability of 83.40%
