Tolerances for a new assembly call for weights between 32 and 33 pounds. The assembly is made using a process that has a mean of 32.6 pounds with a population standard deviation of .22 pounds. The process population is normally distributed.

a. Is the process capable?

b. If not, what proportion will meet tolerances?

c. Within what values will 99.5% of sample means of this process fall if the sample size

is constant at 10 and the process is stable?
