Textbook Question

Chapter 17, Problem 59CE

Each gum drop in two bags of Sathers Gum Drops was weighed (to the nearest .001 g) on a sensitive Mettler PE 360 Delta Range scale. After removing one outlier (to improve normality), there were 84 gum drops in the sample, yielding an overall mean x ¯ = 11.988 g and a pooled standard deviation s = .2208 g. (a) Use these sample statistics to construct control limits for an x ¯ chart, using a subgroup size n = 6. (b) Plot the means shown below on your control chart. Is the process in control? (c) Prepare a histogram and/or normal probability plot for the pooled sample. Does the sample support the view that gum drop weight is a normally distributed random variable? Explain.

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.
