Textbook Question

Chapter 7.3, Problem 13AYU

Putting It Together: Demon Roller Coaster Retrieve the data 7_3_13 at www.pearsonhighered.com/sullivanstats using the file format of your choice for the text you are using. The data represent the time spent waiting in line (in minutes) for the Demon Roller Coaster for 100 randomly selected riders.

a. Draw a relative frequency histogram with lower class limit of the first class equal to 0 and class width 20.
b. Comment on the shape of the distribution.
c. Draw a normal probability plot to assess the normality of the random variable “wait time.”

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
