To determine if their 2.50 inch steel handles are properlyadjusted, Kane Manufacturing has decided to use an x‾x‾-Chart whichuses the range to estimate the variability in the sample.
Step 1 of 7:
What is the Center Line of the control chart? Round your answerto three decimal places.
Step 2 of 7:
What is the Upper Control Limit? Round your answer to threedecimal places.
Step 3 of 7:
What is the Lower Control Limit? Round your answer to threedecimal places.
Step 4 of 7:
Use the following sample data, taken from the next time period,to determine if the process is \"In Control\" or \"Out ofControl\".
Observations: 2.52,2.53,2.44,2.52,2.5,2.46
Sample Mean: 2.495
Step 5 of 7:
Use the following sample data, taken from the next time period,to determine if the process is \"In Control\" or \"Out ofControl\".
Observations: 2.46,2.53,2.5,2.5,2.5,2.53
Sample Mean: 2.5033
Step 6 of 7:
Use the following sample data, taken from the next time period,to determine if the process is \"In Control\" or \"Out ofControl\".
Observations: 2.56,2.48,2.58,2.59,2.55,2.56
Sample Mean: 2.5533
Step 7 of 7:
Based on the control limits established, what is the probabilitythat the production manager will conclude that the process is \"Outof Control\", when the process is actually \"In Control\"? Round youranswer to three decimal places.
