The company Best Burger Inc serves hamburgers, hot dogs, fries, among other things. The restaurant says the fat content per burger is 15 grams. Recently, some customers complained that the fat content appears to be greater than 15 grams. The operations manager randomly selects 20 hamburgers and measures their fat content in grams. The manager makes the corresponding control chart and makes improvements in the process to lower the rate of customer complaints. After some time, he decides to take another sample of 20 burgers and measures their amount of fat. The data that the manager sampled:

	First sample	Second sample
Burguer	Fat	Fat
1	15,5	14,9
2	12,3	15
3	15,4	15,4
4	16,5	15,3
5	15,9	15,2
6	17,1	15,1
7	16,9	14,9
8	14,3	14,8
9	19,1	15,6
10	18,2	14,5
11	18,5	15,3
12	16,3	15,8
13	20	15
14	19	15
15	15,6	14,3
16	13,5	15,3
17	14	15,2
18	16,5	14,7
19	19	15,1
20	18,6	14,7

Answer the following questions:

A correct analysis of the pre-improvement process would look like: a) Statistically, the clients were right; according to the sample, the process did not comply with the fat speciations. b) Statistically the clients were not right; according to the sample, the process did meet the specifications for grams of fat. c) There is insufficient evidence to conclude that the customer was or was wrong about the grams of fat in the burger.

A correct analysis of the process after the improvement would look like: a) The upgrade did work; it reduced the grams of fat that the burgers had and there seems to be no area of opportunity with respect to the specification (there seems to be no problem meeting the specification). b) The upgrade didn't work; the statistics seem to be unchanged after the improvement. c) The upgrade did work; reduced the grams of fat that the burgers had but there is still a large area of opportunity regarding the specification (possibility of not meeting).

The change in the center line of the variable of interest was: a) 1.579 b) 1.55 c) 1.65 d) 1.479

The change in dispersion can be summarized as: a) The variation was not affected after enhancement and can be clearly seen at the control limits. b) The variation decreased and can be clearly seen at the control limits.
