Question 1 5 pts Leah's Toys makes rubber balls. The current process is capable of producing balls that weigh, on average, 7.8 ounces. The tolerance limits for the process are +/- 0.5 ounces from the average weight. In order for Leah's process to achieve Six Sigma quality levels with regard to the weight of the balls, the standard deviation must not exceed ounces (state the answer at the precision level of 2-decimal places).

(5 points)A bottling plant wants to control the amount of soft drink it puts in each can. They decide to periodically sample batches of cans to measure the average amount of soft drink put in each can, and track that data over time to see if the filling process is behaving the way they would expect. Identify which type of quality tool would be appropriate to use, and briefly explain why you think that tool is the best choice. (If...

Question 1 (1 point) A customer wants to estimate the average delivery time of a pizza from the local pizza parlor. Over the course of a few months, the customer orders 29 pizzas and records the delivery times. The average delivery time is 23.69 with a standard deviation of 7.212. If the customer estimates the time using a 95% confidence interval, what is the margin of error? Question 1 options: 1) 0.7137 2) 2.2782 3) 2.7433 4) 1.3392 5) 2.739...
