Specifications for a part for a 3-D printer state that the part should weigh between 25.5 and 26.5 ounces. The process that produces the parts has a mean of 26.0 ounces and a standard deviation of 22 ounce. The distribution of output is normal. Use Table-A. a.What percentage of parts will not meet the weight specs? (Round your "z" value and final answer to 2 decimal places.) Percentage of parts % b.Within what values will 99.74 percent of the sample means of this process fall if samples of n = 12 are taken and the process is in control (random)? (Round your answers to 2 decimal places.) Lower value Upper value c. Using the control limits from part b, would the following sample means be in control? 24.52, 24.53, 24.44, 24.51, 24.41, 24.39 This process is in control. O This process is not in control
