- In 2014, the per capita consumption of soft drinks in the United States was reported to be 42.1 gallons. Assume that the per capita consumption of soft drinks in the United States is approximately normally distributed with a mean of 42.1 gallons and a standard deviation of 13 gallons.

1) What is the probability that someone in the United States consumed more than 60 gallons of soft drinks in 2014?

2) What is the probability that someone in the United States consumed between 15 and 30 gallons of soft drinks in 2014?

3) Ninety-five percent of the people in the United States consumed less than how many gallons of soft drinks?

Step 1

**1.**

Probability that someone consumed more than 60 gallons of soft drinks can be obtained by entering the formula **“=1-NORM.DIST(60,42.1,13,TRUE)”** in EXCEL software.

Step 2

**2.**

Probability that someone consumed between 15 and 30 gallons of soft drinks can be obtained by entering the formula **&ldq...**
