Assume the random variable x is normally distributed with mean u = 90 and standard deviation o=5. Find the indicated probability.
P(X<80) =
(Round to four decimal places as needed.)

Given:

Let the random variable x is normally distributed with mean and

We need to determine the probability of

Probability of :

The formula to determine the value of is given by

Thus, we have;

Simplifying, we get;

Using the normal distribution table, the value of -2 is given by 0.0228

Thus, the value of is 0.0228

17   x 256=4352
