    Let's assume you have taken 100 samples of size 36 each from a normally distributed population. Calculate the standard deviation of the sample means if the population's variance is 25.

    Find P(9 < x < 15) when mu = 12 and sigma = 2. Write your steps in probability notation.

    Find P(x = 13) for a sample taken from a normally distributed population with mu = 15 and sigma = 3.
