C-E please Suppose that the amount of time that students spend studying in the library in one sitting is normallydistributed with mean 41 minutes and standard deviation 21 minutes. A researcher observed 10 studentswho entered the library to study. Round all answers to 4 decimal places where possible.a. What is the distribution of X? X - N(b. What is the distribution of a? a N(c. What is the distribution of x? ) x - Nd. If one randomly selected student is timed, find the probability that this student's time will bebetween 33 and 38 minutes.e. For the 10 students, find the probability that their average time studying is between 33 and 38minutes.f. Find the probability that the randomly selected 10 students will have a total study time less than 320minutes.g. For part e) and f), is the assumption of normal necessary? O NoO Yesh. The top 15% of the total study time for groups of 10 students will be given a sticker that says "Greatdedication". What is the least total time that a group can study and still receive a sticker?minutes
