1. 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. 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.Withio what values will 99.74 percent of the sample means of this process full 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 2. An automatic filling machine is used to fill 1-liter bottles of cola. The machine's output is approximately normal with a mean of 0.99 liter and a standard deviation of 0.04 liter. Output is monitored using means of samples of 26 observations. a. Determine upper and lower control limits that will include roughly 97 percent of the sample means when the process is in control. (Do not round intermediate calculations. Round z value to 2 decimal places. Round your answers to 4 decimal places.) Upper control limits Lower control limits liter liter 5. A medical facility does MRIs for sports injuries.
