There is a 3 percent error rate at a specii c point in a production process. If an inspector is placed at this point, all the errors can be detected and eliminated. However, the inspector is paid $8 per hour and can inspect units in the process at the rate of 30 per hour. If no inspector is used and defects are allowed to pass this point, there is a cost of $10 per unit to correct the defect later on. Should an inspector be hired?

A media personality argues that global temperatures are not rising, because every year an increase is reported, such as 0.09 degrees C. The difference from the previous year is less than the margin of error of about 0.13 degrees C, so that difference should be ignored. What is a strong counter argument? The difference is only 0.4 but that is still a significant change. The change of 0.9 is not a lot and thus should be ignored. The margin of error is larger than the increase so we should consider it an issue just extra information and thus can be ignored. The margin of error is quite small compared to the change year over year, so it is a significant issue.
