Table A Areas under the normal curve, 0 to z Specifications for a part for a 3-D printer state that the part should weigh between 24.3 and 25.3 ounces. The process that produces the parts has a mean of 24.8 ounces and a standard deviation of .23 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=6 are taken and the process is in control (random)? (Round your answers to 2 decimal places.) Lower value?? Upper value
