Page 456 1. Specifications for a part for a 3-D printer state that the part should weigh between 24 and 25 ounces. The process that produces the parts has a mean of 24.5 ounces and a standard deviation of .2 ounce. The distribution of output is normal. a. What percentage of parts will not meet the weight specs? b. Within what values will 95.44 percent of the sample means of this process fall if samples of n = 16 are taken and the process is in control (random)? 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

1. Specifications for a part for a 3-D printer state that the part should weigh between 24 and 25 ounces. The process that produces the parts has a mean of 24.5 ounces and a standard deviation of .2 ounce. The distribution of output is normal. Page 456 a. What percentage of parts will not meet the weight specs? b. Within what values will 95.44 percent of the sample means of this process fall if samples of n = 16 are taken and the process is in control (random)? 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
