Mean = 56.84 , Variance = 5.094 , Standard Deviation = 2.257 , Range = 9 , Median = 57
Use this dataset, answer the following questions. Enter the number with at least 3 decimal places.
1. Suppose the upper specification limit of the dimension should be 60. How many sigma is the upper specification limit away from its mean?
2. Suppose the measurements are normally distributed. Estimate the defect rate using the mean and standard deviation.
3. m = 58 and specification limits are 54 and 62. Determine Cp and Cpk.
Homework Answers
1)
z =(X - mean)/sd = (60 - 56.84)/2.257
= 1.4
upper specification limit is 1.4 sigma above from its mean

West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the time above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to...
