  1. List data set: List the given data set.\newlineThe data set provided is: 70,39,114,39,52,108,10170, 39, 114, 39, 52, 108, 101.
  2. Calculate mean: Calculate the mean (average) of the data set.\newlineTo find the mean, sum all the data points and divide by the number of data points.\newlineMean = (70+39+114+39+52+108+101)/7(70 + 39 + 114 + 39 + 52 + 108 + 101) / 7\newlineMean = 523/7523 / 7\newlineMean 74.714\approx 74.714
  3. Calculate deviations: Calculate the deviations from the mean for each data point. This involves subtracting the mean from each data point. Deviations: (7074.714)(70 - 74.714), (3974.714)(39 - 74.714), (11474.714)(114 - 74.714), (3974.714)(39 - 74.714), (5274.714)(52 - 74.714), (10874.714)(108 - 74.714), (10174.714)(101 - 74.714)
  4. Square deviations: Square each deviation to get the squared deviations.\newlineSquared deviations: (7074.714)2(70 - 74.714)^2, (3974.714)2(39 - 74.714)^2, (11474.714)2(114 - 74.714)^2, (3974.714)2(39 - 74.714)^2, (5274.714)2(52 - 74.714)^2, (10874.714)2(108 - 74.714)^2, (10174.714)2(101 - 74.714)^2
  5. Sum squared deviations: Sum the squared deviations.\newlineSum of squared deviations = (7074.714)2+(3974.714)2+(11474.714)2+(3974.714)2+(5274.714)2+(10874.714)2+(10174.714)2(70 - 74.714)^2 + (39 - 74.714)^2 + (114 - 74.714)^2 + (39 - 74.714)^2 + (52 - 74.714)^2 + (108 - 74.714)^2 + (101 - 74.714)^2\newlineSum of squared deviations 22.449+1277.571+1538.449+1277.571+517.571+1111.449+689.571\approx 22.449 + 1277.571 + 1538.449 + 1277.571 + 517.571 + 1111.449 + 689.571\newlineSum of squared deviations 5434.631\approx 5434.631
  6. Calculate variance: Divide the sum of squared deviations by the sample size minus one to get the variance.\newlineSince we have 77 data points, we divide by 66 (n1n-1).\newlineVariance = 5434.631/65434.631 / 6\newlineVariance 905.772\approx 905.772
  7. Find standard deviation: Take the square root of the variance to find the sample standard deviation.\newlineSample standard deviation = 905.772\sqrt{905.772}\newlineSample standard deviation 30.096\approx 30.096
