A normal distribution of scores has a standard deviation of 10. Find the z-scores
corresponding to each of the following values:
a) A score of 60, where the mean score of the sample data values is 40.

Answer 1

Answer:

Z-score is 2

Step-by-step explanation:

a) N (40, 10^2)

Use Z-score formula (can be found in the internet, with miu and sigma symbols)

$z = \frac{60 - 40}{10} \\ z = \frac{20}{10} \\ z = 2$
