Question

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 1.6 ounce packets. To reduce the chances of shorting the customer, product design specifications call for the packet-filling process average to be set at 44.0 grams so that the average net weight per box of 10 packets will be 440 grams. Tolerances are set for the box to weigh 440 14 grams. The standard deviation for the packet-filling process is 1.03 grams. The target process capability ratio is 1.67. One day, the packet-filing process average weight drifts down to 43.0 grams. Is the packaging et process capability ratio is 1.67. One day, the for the box to weigh 4401 14 grams. The standard de sef ar 44.0 grams so that the process capable? Is an adjustment needed? Since the process capability index, Cpk, is the process (Enter your rosponde rounded to three decimal places.)

Cliven, USL2440+14 2454 LSL = 440-142 426 sample size (n)=10 Now, 5 = 1.03 xVhz 1.03 XTO= 3.2571 Target Cpk =167 Now average drifts to 43 Net total weight (X) = 43110 = 430 → 4pk = min u USLX, xlsiz § 454-430 430-426 2. [ 313.2577) 313,2571) = 0.409 - Since process capability index 4k is 0.409 which is less than 167, process is not capable. USL-X X-isu 36
