Suppose X ~ N(5, 6). Suppose x = 12. Calculate the value of Z (2 marks). Z = (x-µ)/σ
Question
Solution 1
Sure, let's calculate the Z value step by step.
Step 1: Identify the given values. Here, the mean (µ) is 5, the standard deviation (σ) is the square root of the variance, so σ = sqrt(6), and x = 12.
Step 2: Substitute these values into the Z formula. The Z score formula is Z = (x - µ) / σ.
