1. A good quality lawnmower is supposed to start at the firsttry. In the third quarter, 50 craftsman lawnmowers are startedevery 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 6days are 4, 5, 4, 6, 7, 6, respectively. Was the quality oflawnmower changed in the fourth quarter?
2.There have been complaints that the sports page of the DubuqueRegister has lots of typos. The last 6 days have been examinedcarefully, and the number of typos/page is recorded below. Is theprocess in control?
