11) Difference in Means: A fast-food restaurant uses an
automated filling machine to pour its drinks. The machine has
different settings for large (L) and medium (M) and follows an
approximately normal distribution. The amount of liquid for L
has a mean of 27 ounces and a standard deviation of 0.8 oz. The
amount of liquid for M has a mean of 17 ounces and standard
deviation of 0.5 oz. Estimate the probability that difference in
sample means of 20 L cups and 25 M cups is within .25 ounces of
the true difference in means. (FRQ Style)

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.
