3. If x is a normally distributed continuous random variable with µ = 25 and σ = 4 , find the following:

e. What is the value of x where approximately 25% of the population lies greater than x?

f. If x = 18.9, what is the percentile associated with x?

g. Find the limits on x if x must fall in the middle 50% of all scores.

h. Find the limits on x if only 5% of the population values are excluded from both the low values of x and the high value of x.
