Textbook Question

Chapter 6, Problem 12PS

In 2015, the per capita consumption of soft drinks in the United States was reported to be 650 eight-ounce servings.

Assume that the per capita consumption of soft drinks in the United States is approximately normally distributed with a mean of 650 eight-ounce servings and standard deviation of 100 eight-ounce servings.

a. What is the probability that someone in the United States consumed more than 750 eight-ounce servings in 2015?

b. What is the probability that someone in the United States consumed between 450 and 500 eight-ounce servings in 2015?

c. What is the probability that someone in the United States consumed less than 450 eight-ounce servings in 2015?

d. Ninety- nine percent of the people in the United States consumed less than how many servings of eight-ounce soft drinks in 2015?

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.
