1. At Quickie Car Wash, the wash process is advertised to take less than 6 minutes. Consequently, management has set a target average of 330 seconds for the wash process. Suppose the average range for a sample of 10 cars is 8 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process.

Part 2 The UCLR equals 14.216 seconds and the LCLR equals 1.784 seconds. (Enter your responses rounded to two decimal places.)

Part 3 The UCLx equals enter your response here seconds and the LCLx equals enter your response here seconds. (Enter your responses rounded to two decimal places.) ANSWER BOLDED IN PART 3.

2.

Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of 15 ounces (425 grams) per box. Each box contains 10 individual 1.5-ounce packets. To reduce the chances of shorting the customer, product design specifications call for the packet-filling process average to be set at 43.0 grams so that the average net weight per box of 10 packets will be 430 grams. Tolerances are set for the box to weigh 43015 grams. The standard deviation for thepacket-filling process is 1.03 grams. The target process capability ratio is 1.67. One day, the packet-filling process average weight drifts down to 42.0 grams. Is the packaging process capable? Is an adjustment needed?

Since the process capability index, Cpk, is () enter your response here, the process () is not capable is capable
