The average THC content of marijuana sold on the street is 10.9%. Suppose the THC content is normally distributed with standard deviation of 1%. Let X be the THC content for a randomly selected bag of marijuana that is sold on the street. Round all answers to 4 decimal places where possible,

a. What is the distribution of X? X ~ N( , )

b. Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 12.5.

c. Find the 77th percentile for this distribution. %
