Question
The average THC content of marijuana sold on the street is 9.6%. Suppose the THC content is normally distributed with a standard deviation of 1%. Let \( X \) be the THC content for a randomly selected bag of marijuana that is sold on the street.

a. What is the distribution of \( X \)? \( X \sim N( \, \boxed{9.6} \, , \, \boxed{1} \, ) \)

b. Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.1. Round to 4 decimal places. \( \boxed{ } \)

c. Find the 72nd percentile for this distribution. Round to 2 decimal places. \( \boxed{ } \% \)
