If X is a normal variate with mean 16 and standard deviation 4, then the value of standard normal variate Z corresponding to X = 17 is: |
1.25 -1.25 -0.25 0.25 |
0.25 |
The correct answer is Option (4) → 0.25 Given: X ~ N(μ = 16, σ = 4) Standard normal variate: Z = (X − μ) / σ For X = 17: Z = (17 − 16) / 4 Z = 1 / 4 Z = 0.25 |
