Given a normally distributed random variable X with a µ=5 and σ=2, find P(X>8).Question 4Answera.0.0001b.0.9270c.0.1862d.0.0668
Question
Solution 1
To find the probability that a normally distributed random variable X is greater than 8 (P(X>8)), we first need to convert the X value to a z-score. The z-score is a measure of how many standard deviations an element is from the mean.
The formula for finding the z-score is:
Z = (X - µ) / σ
