Question 8 (1 point) Let X be normally distributed with mean μ = 3 and σ = 2. Find P(X ≤ 1.5) by converting X into a standard normal random variable.
Added by Emilio E.
Step 1
First, we need to standardize X by subtracting the mean and dividing by the standard deviation: Z = (X - μ) / σ where μ = 3 and σ = 2. So, Z = (X - 3) / 2. Show more…
