Suppose that the amount of time that students spend studying in the library in one sitting is normally distributed with mean 41 minutes and standard deviation 22 minutes. A researcher observed 17 students who entered the library to study. Round all answers to 4 decimal places where possible. For the 17 students, find the probability that their average time studying is between 34 and 38 minutes. Find the probability that the randomly selected 17 students will h

For the 17 students, find the probability that their average time studying is between 34 and 38 minutes.
Find the probability that the randomly selected 17 students will have a total study time more than 765 minutes.
The top 10% of the total study time for groups of 17 students will be given a sticker that says "Great dedication". What is the least total time that a group can study and still receive a sticker? (minutes)
