Leah's Toys makes rubber balls. The current process is capable of producing balls that weigh, on average, 3.2 ounces, with a standard deviation of 0.38 ounces. a. The upper and lower tolerance limits are 3.5 ounces and 2.9 ounces respectively: The process capablity ratio is (Enter your response rounded to three decimal places.) Leah's capable of meeting the tolerance limits 99.7% of the time. b. In order to exactly meet the tolerance limits 99.7% of the time, Leah's Toys would need to reduce the standard deviation to to two decimal piaces.) c. Suppose Leah's Toys invests in process improvements that lower the standard doviation to just 0.08 ounces. This enough for Leah's to achieve Six Sigma quality lovels with regard to the weight of the balls, because a new process capability ratio is (Enteryour response rounded to throe decimal places.)
