Question Sugar canes have lengths, X , that are normally distributed with mean 365.45 centimeters and standard deviation 4.9 centimeters. What is the probability of the length of a randomly selected cane being between 360 and 370 centimeters?  Round your answer to four decimal places. The mean is μ=365.45 , and the standard deviation is σ=4.9 . As the probability between two values is to be calculated, subtract the probability of the lower value from the higher value. In this case, y...

MATH 225N Week 5 Understanding Normal Distribution (QUESTIONS & ANSWERS)

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...
