1. Find the range, variance, and standard deviation. Assume the data represent samples, and use the shortcut formula for the unbiased estimator to compute the variance and standard deviation:
The normal daily high temperatures (in degrees Fahrenheit) in January for 10 selected cities are as follows:
50, 37, 29, 54, 30, 61, 47, 38, 34, 61
The normal monthly precipitation (in inches) for these same 10 cities is listed here: 4.8, 2.6, 1.5, 1.8, 1.8, 3.3, 5.1, 1.1, 1.8, 2.5
Which set is more variable?
