Q. Based on the following calculator output, determine the inter-quartile range of the dataset. 1-Var-Stats xˉ=216.857142857Σx=1518Σx2=356184Sx=67.0756502551σx=62.0999852115n=7minX=108Q1=135Med2=245Q3=267maxX=278Answer:
Identify Q1 and Q3: Identify the first quartile (Q1) and the third quartile (Q3) from the calculator output.From the output, we have Q1=135 and Q3=267.
Calculate IQR: Calculate the inter-quartile range (IQR) using the formula IQR=Q3−Q1.IQR=267−135=132.
Verify Values and Subtraction: Verify that the values used for Q1 and Q3 are correct and that the subtraction is done correctly.Q1=135 and Q3=267 are given by the calculator output. The subtraction 267−135=132 is correct.
