The scores for the top 10 ice sculptures in an ice sculpture competition can be found below. Score 174 179.7 172.8 180.6 174.7 174.6 178.5 174.6 179.1 171.8 Estimate the standard deviation using the range rule of thumb:

Use the magnitudes (Richter scale) of the 120 earthquakes listed in the accompanying data table. Use technology to find the range, variance, and standard deviation. If another value, 8.00, is added to those listed in the data set, do the measures of variation change much? Click the icon to view the table of magnitudes. Magnitudes Without the extra data value, the range is (Type an integer or decimal rounded to three decimal places as needed.) 3.28 2.82 2.83 1.96 1.70 2.55 O 2.45 3.40 3.95 1.59 2.91 1.63 2.53 2.42 2.97 2.93 3.99 2.54 2.43 1.83 2.17 2.35 2.00 3.01 2.80 3.86 2.93 2.08 1.86 2.35 2.38 3.45 3.43 1.55 2.54 1.49 2.19 3.09 2.28 3.25 1.98 1.91 2.42 2.95 2.14 2.33 2.56 2.89 1.48 1.91 2.68 1.81 3.65 2.70 1.45 3.61 3.14 2.57 1.51 1.41 2.83 2.87 2.18 1.67 3.21 1.39 1.75 2.35 1.14 2.36 2.48 1.79 2.00 3.03 1.94 2.42 1.86 2.25 2.33 3.17 4.01 2.08 1.49 2.31 2.33 2.56 2.59 2.21 2.75 2.45 2.73 3.58 2.81 2.80 3.25 1.76 4.68 3.23 2.38 2.00 3.83 2.39 2.85 3.38 2.69 2.31 2.83 2.78 2.43 2.34…

← The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance, and standard deviation of the population data set. 2, 10, 15, 4, 12, 9, 13, 10, 5, 7 The range is 13. (Simplify your answer.) The population mean is 8.7. (Simplify your answer. Round to the nearest tenth as needed.) The population variance is 15.6. (Simplify your answer. Round to the nearest tenth as needed.) The population standard deviation is (Simplify your answer. Round to the nearest tenth as needed.)
