Answer 2

Answer: the Z-score test result of 1800 points is 1.33

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 find the Z-score test result of 1800 points

For x = 1800,

z = (1800 - 1700)/75 = 100/75 = 1.33
