A process filling small bottles with baby formula has a target of 3 ounces +/- 0.150 ounce. Two hundred bottles from the process were sampled. The results showed the average amount of formula placed in the bottles to be 3.042ounces. The standard deviation of the amounts was 0.034ounce. Determine the value of Cpk. Roughly what proportion of bottles meet thespecifications?
Part 2 The process capability index (Cpk) is (round your response to three decimal places).
Part 3 Slightly more than (answer choice of 99.99, 95.45, 90, 99.73, or 80%) of the bottles meet the specifications.
