**Title: Analyzing the Distribution of THC Content in Marijuana****Introduction:**The average THC content of marijuana sold on the street is 9.4%. Suppose the THC content is normally distributed with a standard deviation of 2.6%. Let X be the THC content for a randomly selected bag of marijuana that is sold on the street.**Questions:**a. **What is the distribution of X?**- X ~ N(9.4, 2.6)b. **Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 7.9.** - Round your answer to 4 decimal places.c. **Find the 65th percentile for this distribution.**- Round your answer to 2 decimal places.**Instructions:**Complete the blanks by calculating the required probabilities and percentiles based on the normal distribution.

From the provided information, Mean (µ) = 9.4% Standard deviation (σ) = 2%
