1. Suppose that X is normally distributed with mean 95 and standard deviation 15.A. What is the probability that X is greater than 123.95?B. What value of X does only the top 12% exceed?2.(2 points) Fluorescent lighbulbs have lifetimes that are normally distributed with a mean of 6.9 years and a standard deviation of 1.6 years. The figure below shows the distribution of lifetimes of fluorescent lightbulbs. Calculate the shaded area under the curve. Express your answer in decimal form with at least two decimal placeaccuracy.
