HW Score: 83.86%, 8.39 of 10 points Points: 0.1 of 1 Save 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, 7.50, 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. Without the extra data value, the range is 3.54 (Type an integer or decimal rounded to three decimal places as needed.) Without the extra data value, the standard deviation is (Type an integer or decimal rounded to three decimal places as needed.). n example Get more help F3 Search 10+ 3 F4 BQ 4 $ F5 95 F6 ♡ Magnitudes 3.32 2.81 2.79 1.04 1.69 2.52 2.42 3.43 3.04 1.60 2.88 1.60 2.54 3.98 2.49 2.44 1.84 2.19 2.45 3.01 2.93 2.35 2.00 3.01 2.77 3.82 2.97 2.09 184 233 2.38 3.45 3.41 1.55 2.53 1.50 2.22 3.11 2.29 3.25 1.95 1.93 2.40 2.96 2.57 1.50 2.17 2.34 1.91 2.73 2.88 1.83 3.68 2.68 1.45 3.57 3.12 2.59 155 1.43 2.83 2.85 2.19 1.68 3.19 1.38 1.72 2.37 1.15 2.35 2.48 1.81 2.00 3.02 1.94 2.45 1.85 2.24 2.36 3.17 4.04 2.07 1.49 228 2.30 2.57 2.54 2.19 2.78 2.46 2.74 3.58 281 2.75 3.27 1.77 4.69 3.20 2.37 2.00 3.89 2.38 2.85 2.69 2.31 2.83 2.79 2.44 3.38 2.33 2.42 2.43 2.49 2.70 2.45 282 2.69 2.70 2.42 Print Done B 向 F7 F8 F9 F10 F11 4 4+ Λ & * ) F12 A 6 7 8 9 0 X Fin Lock Final check 7:07 PM 9/1/2024 Insert Prt Sc Del Backsp he difference between the maximum data value and the minimum data val Range (maximum data value) - (minimum data value) = deviation of a set of sample values, denoted by s, is a measure of how m ay from the mean.
