Week 5 Assignment: Understanding Normal Distribution
Question
John averages 58 words per minute on a typing test with a standard deviation
of 11 words per minute. Suppose John's words per minute on a typing test are
normally distributed. Let X= the number of words per minute on a typing test.
Then X∼N(58,11).
Answer: 1.273, 58, 1.273
Question
The graph below shows the graphs of several normal distributions, labeled A, B, and C, on the
same axis. Determine which normal distribution has the largest standard deviation.
Answer: C
Question
Isabella averages 152 points per bowling game with a standard deviation
of 14.5 points. Suppose Isabella's points per bowling game are normally distributed.
Let X= the number of points per bowling game. Then X∼N(152,14.5).
Answer: 2.414, 152, 2.414
