Suppose X is a normally distributed random variable with mean 100 and standard deviation 10. Which of the following excel functions will find x<105?
a. = NORM.DIST(105, 1, 0, TRUE)
b. = 1-NORM.DIST(105, 100, 10, TRUE)
c. = NORM.DIST(100, 1, 0, TRUE)
d. = NORM.DIST(105, 100, 10, TRUE)
e. = NORM.DIST(100, 105, 10, TRUE)
