Specifications for a part for a 3-D printer state that the part should weigh between 24.5 and 25.5 ounces. The process that produces the parts has a mean of 25.0 ounces and a standard deviation of .25 ounce. The distribution of output is normal. UseTable-A.

a.What percentage of parts will not meet the weight specs?(Round your "z" value and final answer to 2 decimal places.)

b.Within what values will 99.74 percent of the sample means of this process fall if samples ofn= 8 are taken and the process is in control (random)?(Round your answers to 2 decimal places.)
