The distribution of scores on a statistics exam is T(49, 75, 92).

a) Find the mean. (Round your answer to 2 decimal places.)

Mean = 72

b) Find the standard deviation. (Round your answer to 2 decimal places.)

SD = 8.84

c) Find the probability that a score will be less than 72. (Round your answer to 4 decimal places.)

part c as the mean is also 72 hence the probability of less than 72 is 0.5
