Q. Based on the following calculator output, determine the population standard deviation of the dataset, rounding to the nearest 1ooth if necessary. 1-Var-Stats xˉ=106.142857143Σx=743Σx2=80877Sx=18.3160091307σx=16.9573294008n=7minX=77Q1=91Med2=107Q3=120maxX=131Answer:
Identify symbol for population standard deviation: Identify the symbol for population standard deviation in the calculator output.The symbol for population standard deviation is σx in the calculator output.
Locate value of standard deviation: Locate the value of the population standard deviation in the calculator output.The value given for "sigma x" is 16.9573294008.
Round standard deviation: Round the population standard deviation to the nearest hundredth. Rounding 16.9573294008 to the nearest hundredth gives us 16.96.
Verify rounding accuracy: Verify that the rounding is done correctly. 16.9573294008 rounded to two decimal places is indeed 16.96.
