Question

Given that X ~N(μ=10, σ=5) compute the following probabilities:

P(15 ≤ X ≤ 25) is:

Step 1

Here *X *follows normal distribution with mean 10 and standard deviation 5.

The probability of 15 ≤ X ≤ 25 can be found as,

Step 2

Using the Excel formula, ‘=NORM.DIST(25,10,5,TRUE)’, the value of P(X≤25) =0.99865.
