Textbook Question

Chapter 5, Problem 39PE

A popular soft drink is sold in 2-liter 2,000-milliliter bottles. Because of variation in the filling process, bottles have a mean of 2 , 000 milliliters and a standard deviation of 18 , normally distributed.

If the process fills the bottle by more than 30 milliliters , the overflow will cause a machine malfunction. What is the probability of this occurring?
What is the probability of underfilling the bottles by at least 10 milliliters ?

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.
