1. A good quality lawnmower is supposed to start at the first try. In the third quarter, 50 craftsman lawnmowers are started every day and an average of 4 did not start. In the fourth quarter, the number of lawnmower did not start (out of 50) in the first 6 days are 4, 5, 4, 6, 7, 6, respectively. Was the quality of lawnmower changed in the fourth quarter?
2.There have been complaints that the sports page of the Dubuque
Register has lots of typos. The last 6 days have been examined
carefully, and the number of typos/page is recorded below. Is the
process in control?
Day | Mon | Tue | Wed | Thurs | Fri | Sat |
Typos | 2 | 1 | 5 | 3 | 4 | 0 |
1) the quality of the lawnmower doesn't change in the 4th quarter. And the process is in control.
2) the process is in control.
