Question

If μ=52, σ=15, and X=80, the z-score would be: (a) -1.87 (b) -0.93 (c) 0.93 (d) 1.87.

Answer 1

The z-score can be calculated using the formula: z = (X - μ) / σ. Given that μ = 52, σ = 15, and X = 80, the z-score is 1.87.

Step-by-step explanation:

The z-score can be calculated using the formula:

z = (X - μ) / σ

where X is the value, μ is the mean, and σ is the standard deviation.

Given that μ = 52, σ = 15, and X = 80, we can calculate the z-score:

z = (80 - 52) / 15 = 1.87

Therefore, the z-score is 1.87.
