Question

Use the magnitudes (Richter scale) of the earthquakes listed in the data set below. Use technology to find the range, variance, and standard deviation. 1.52 2.96 0.23 2.68 2.16 2.34 1.92 1.82 2.47 0.56 1.82 2.47 1.39 1.58 1.66 0.21 1.92 0.64 2.88 1.98 1.12 2.92 2.09 0.68 2.35 2.46 0.47 0.39 1.69 1.06 2.75 0.47 0.95 1.18 2.23 1.56 2.24 0.58 2.38 1.83 1.06 2.79 2.38 2.39 0.75 0.95 0.23 2.87 0.31 2.74 2.89 2.14 The range of the data set is. (Round to three decimal places as needed.) The variance, s^2, of the data set is. (Round to three decimal places as needed.) The standard deviation, s, of the data set is. (Round to three decimal places as needed.)

Explanation / Answer

putting the above data in ascending order

here range =maximum -minimum=2.96-0.21=2.75

varaince s2=0.772

std deviation s=0.879
