Understanding Normal Distribution: week #5 1. Lexie averages 149 points per bowling game with a standard deviation of 14 points. Suppose Lexie's points per bowling game are normally distributed. Let X= the number of points per bowling game. Then X∼N(149,14). Suppose Lexie scores 186 points in the game on Tuesday. The z-score when x = 186 is 2.643 - no response given. The mean is 149 - no response given. This z-score tells you that x = 186 is 2.643- no response given standard deviation...

MATH 225N WEEK 5 DISCUSSION, THE NORMAL DISTRIBUTION Many variables in medicine follow a normal distribution where there are approximately an equal number of values below the mean as above the mean. Describe two variables that you work with that would probably follow a normal distribution. Also note which of the two variables would be likely to have a larger standard deviation and why. Statistical data is indispensable to physicians, and the knowledge of statistics is essential not only fo...
