Question

A packaging line fills nominal 64-ounce tomato juice jars with a quantity of juice having a normal distribution with a mean of 64.30 ounces. The process should have a standard deviation smaller than 0.15 ounces per jar. (A larger standard deviation leads to too many under filled and overfilled jars.) A random sample of 24 jars is taken every hour to evaluate the process. The data is given in data_6. Construct a 95% confidence interval on the process standard deviation. Do the data indicate that the process standard deviation is greater than 0.15?

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.
