Question

In 2008, the per capita consumption of soft drinks in Country A was reported to be 18.83 gallons. Assume that the per capita consumption of soft drinks in Country A is approximately normally distributed, with a mean of 18.83 gallons and a standard deviation of 4 gallons.

98% of the people in Country A consumed less than how many gallons of soft drinks?

The probability is 98% that someone in Country A consumed less than ___ gallons of soft drinks.

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.
