Question

The average score at Laila's favorite golf course is 91, with a standard deviation of 10. In their most recent round at the golf course, Laila scored an 85.

Calculate the z-score for Laila's round of golf.

Answer 1

Based on the given information, we can calculate the z-score for Laila's round of golf using the formula:

z = (x - μ) / σ

where:
x = Laila's score = 85
μ = mean score = 91
σ = standard deviation = 10

Substituting the values, we get:

z = (85 - 91) / 10
z = -0.6

Therefore, the z-score for Laila's round of golf is -0.6.

Answer 2

Step 1. Grab a calculator

Step 2. Solve

Use this z = (x - μ) / σ, where x is the individual score, μ is the mean score, and σ is the standard deviation. 😉

Laila's score (x) is 85, the mean score (μ) is 91, and the standard deviation (σ) is 10.

Plug this into your calculator. If you don't get this answer, you're wrong. 👇
z = (85 - 91) / 10

Simplify it:
z = -6 / 10

Answer is -0.6.
