Reeves Inc. has decided to use an R-Chart to monitor the changes in the variability of their 60.00 pound industrial belts. The quality control manager randomly samples 7 industrial belts and measures the weight of the sample (in pounds) at 18 successive time periods.

Step 1 of 7: What is the Center Line of the control chart? Round your answer to three decimal places.

Step 2 of 7: What is the Upper Control Limit? Round your answer to three decimal places.

Step 3 of 7: What is the Lower Control Limit? Round your answer to three decimal 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 of Control".

Observations: 60.13,59.97,59.98,59.96,59.96,60.02,59.99

Sample Range: 0.17

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 of Control".

Observations: 59.96,59.96,60.03,59.97,60.12,60.03,60.02

Sample Range: 0.16

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 of Control".

Observations: 59.96,60.05,59.98,60.03,59.98,59.98,60.02

Sample Range: 0.09

Step 7 of 7: You, acting as the quality control manager, have concluded that the process is "Out of Control". What is the probability that the process is really "In Control" and you have made a Type I Error? Round your answer to three decimal places.
