Need help with this normal distribution problem. Parts a,b,c. Any instructions on how to use a ti 84 plus calculator would be awesome. Round to 4 decimals where possible. Thanks you!

The average THC content of marijuana sold on the street is 10.2%. Suppose the THC content is normally
distributed with standard deviation of 2%. 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 11.9.
c. Find the 77th percentile for this distribution.
Hint:

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
