A candy bar factory is pouring chocolate into molds to cool. The finished bars are sold as 1.25 ounce bars. The company will lose money if the molds are over-filled. If the molds are under-filled, the weight of the candy bars will be less than the wrapper label says, and the Food and Drug Administration will fine the company for misrepresenting the size of its product. The company wants to create an chart to monitor the weight of the candy bars. Suppose there are 5 samples of size 30 each taken, and their sample means are 1.27, 1.22, 1.26, 1.23, and 1.26 ounces.
What is the centerline value?
______________
The calculated value of s, the sample standard deviation of all nk = (30)(5) = 150 observations, is 0.12 ounces. What is the standard error of the mean of 30 observations?
______________
What are the control limits?
UCL = ______________
LCL = ______________
How is the chart used in this situation?
