Question

Based on the following calculator output, determine the population standard deviation of the dataset, rounding to the nearest 1ooth if necessary.  {:[" 1-Var-Stats "],[ bar(x)=270],[Sigma x=1890],[Sigmax^(2)=512150],[Sx=17.5594229214],[sigma x=16.2568666811],[n=7],[minX=240],[Q_(1)=257],[Med^(2)=274],[Q_(3)=282],[maxX=291]:} Answer:

Identify symbol for population standard deviation: Identify the symbol for population standard deviation in the calculator output. The symbol for population standard deviation in the calculator output is ＂sigma x＂. This is the value we are looking for.Locate value in calculator output: Locate the value of the population standard deviation in the calculator output. The value given for ＂sigma x＂ in the output is 16.2568666811.Round to nearest hundredth: Round the population standard deviation to the nearest hundredth. To round to the nearest hundredth, we look at the third decimal place. If it is 5 or more, we round up. If it is less than 5, we round down. The third decimal place of 16.2568666811 is 6, so we round up the second decimal place from 5 to 6. The rounded population standard deviation is 16.26.
