Hi i am having trouble with a couple questions involving percentiles, here is the question:
1) Adrian's average bowling score is 174, with a standard deviation of 35.
a) In what percent of games does Adrian score less than 200 points? More than 200 points?
b) The top 10% of bowlers in Adrian's league get to play in an all-star game. If the league average is 170, with a standard deviation of 11 points, what average score does Adrian need to have to obtain a spot in the all-star game?
Thank you.
