= OTIME SERIES AND QUALITY CONTROL Interpreting a control chart Each day, an electronics manufacturer creates thousands of small fan motors for computers. The speed (i.e., revolutions per minute) with which the motors run must be in a certain range. Motors that run too slowly will not cool a computer properly; motors that run too fast will wear out prematurely. The following R chart monitors the amount of variability of the speed (in rpm's) of subgroups of 7 motors that have been selected each hour for testing: 1 1 3 Does the rule give an "out Rule # of control" signal? (Check the box that applies) O Yes O No 2 3 O Yes 7 Yes 9 R chart O No 11 • Rule 1: One or more points fall outside one of the chart's control limits O No • Rule 2: Nine points in a row are on the same side of the chart's centerline • Rule 3: Six points in a row are increasing (or decreasing). 13 Subgroup number For a process such as this to be "in statistical control," only random patterns of points should appear on…

The accompanying data represent the weights of various domestic cars and their gas mileages in the city for a certain model year. Suppose that we add Car 12 to the original data. Car 12 weighs 3 comma 3053,305 pounds and gets 1919 miles per gallon a) Compute the linear correlation coefficient with Car 12 included. The linear correlation coefficient with Car 12 included is r-? (Round to three decimal places as needed.) b) Recompute the linear correlation coefficient with Car 13 included. How did this new value affect your result? The linear correlation coefficient with Car 13 included is r-? t) Why does this observation not follow the pattern of the data?
