Question

The weights in ounces of boxes of cereal filled in an assembly line process are normally distributed, with a mean of 56 ounces and a standard deviation of 5.8 ounces. If 25 boxes of cereal are selected at random, then 19% if the time, their mean weight will be greater than how many ounces? Give result accurate to at least 1 decimal place.

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.
