Q. Based on the following calculator output, determine the inter-quartile range of the dataset. 1-Var-Stats xˉ=91.7142857143Σx=642Σx2=69948Sx=42.9484741123σx=39.7625605877n=7minX=33Q1=45Med2=92Q3=117maxX=156Answer:
Identify Quartiles: Identify the first quartile ( extit{Q1}) and the third quartile ( extit{Q3}) from the calculator output.From the output, we have extit{Q1} = 45 and extit{Q3} = 117.
Calculate IQR: Calculate the inter-quartile range (IQR) using the formula IQR=Q3−Q1.IQR=117−45=72.
Verify Values: Verify that the values used for Q1 and Q3 are correct and that the subtraction is done correctly.Q1=45 and Q3=117 are given in the output, and 117−45=72 is the correct subtraction.
