I don’t have the course mean and standard deviation. Use the z-score formula:
time = μ + z·σ
So Ashley’s time = μ + (−1.2)·σ.
If you give me the mean μ and standard deviation σ I’ll compute the numeric time. (Example: if μ = 75 s and σ = 5 s, time = 75 + (−1.2)(5) = 69 s.)
time = μ + z·σ
So Ashley’s time = μ + (−1.2)·σ.
If you give me the mean μ and standard deviation σ I’ll compute the numeric time. (Example: if μ = 75 s and σ = 5 s, time = 75 + (−1.2)(5) = 69 s.)
