Problem 68
Cold weather A meteorologist preparing a talk about global warming compiled a list of weekly low temperatures (in degrees Fahrenheit) he observed at his southern Florida home last year. The coldest temperature for any week was \(36^{\circ} \mathrm{F},\) but he inadvertently recorded the Celsius value of \(2^{\circ} .\) Assuming that he correctly listed all the other temperatures, explain how this error will affect these summary statistics: a. measures of center: mean and median b. measures of spread: range, IQR, and standard deviation
