The level of impurity (in percent) in the product of a certain chemical process is a random variable with probability density function
a. What is the probability that the impurity level is greater than 3%?
b. What is the probability that the impurity level is between 2% and 3%?
c. Find the mean impurity level.
d. Find the variance of the impurity levels.
e. Find the cumulative distribution function of the impurity level.
Step 1 of 5:
Given, the probability density function is
