Textbook Question

Chapter 7.2, Problem 39AYU

NW Chips Ahoy! Cookies The number of chocolate chips in an 18-ounce bag of Chips Ahoy! chocolate chip cookies is approximately normally distributed with a mean of 1262 chips and standard deviation 118 chips according to a study by cadets of the U.S. Air Force Academy.

Source: Brad Warner and Jim Rutledge, Chance 12(1): 10–14, 1999

a. What is the probability that a randomly selected 18-ounce bag of Chips Ahoy! contains between 1000 and 1400 chocolate chips, inclusive?
b. What is the probability that a randomly selected 18-ounce bag of Chips Ahoy! contains fewer than 1000 chocolate chips?
c. What proportion of 18-ounce bags of Chips Ahoy! contains more than 1200 chocolate chips?
d. What proportion of 18-ounce bags of Chips Ahoy! contains fewer than 1125 chocolate chips?
e. What is the percentile rank of an 18-ounce bag of Chips Ahoy! that contains 1475 chocolate chips?
f. What is the percentile rank of an 18-ounce bag of Chips Ahoy! that contains 1050 chocolate chips?

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.
