Question

a. cumulative probabilities for a normally distributed x value

b. the normally distributed x value given a cumulative probability

c. the standard normal z value given a cumulative probability

d. cumulative probabilities for a standard normal z value

I think d) because normal distribution functions are usually used for cumulative probabilities and the S is probably for standard normal which uses z-scores.
