the mean score for a standardized test is 1700 points. the results are normally distributed with a standard deviation of 75 points. what is the z-score test result of 1300 points?

the z score is - 5.33

Step-by-step explanation:

Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = test reults

µ = mean score

σ = standard deviation

From the information given,

µ = 1700 points

σ = 75 points

We want to the Z-score test result of 1300 points.

For x = 1300,

z = (1300 - 1700)/75 = - 400/75 =

- 5.33

r = 78539458390583095803458309458039485093485 or just 3
