Question

complete the following analysis

Explanation:

Step1: Calculate sum of \((x - \bar{x})^2\) for Group 1

Add up all the values in the \((x - \bar{x})^2\) column of Group 1:
\(41.47+30.91 + 55.35+29.59+41.47+308.35+382.59+5.95+6.55+29.59+55.35+55.35+11.83+29.59+344.47+41.47\)
\(=1470.3\)

Step2: Calculate sum of \((x - \bar{x})^2\) for Group 2

Add up all the values in the \((x - \bar{x})^2\) column of Group 2:
\(51.7+51.7+51.7+17.56+392.44+353.82+26.94+7.9+190.72+116.86+38.32+38.32+51.7+67.08+38.32+1.42\)
\(=1405.7\)

Answer:

The sum of \((x - \bar{x})^2\) for Group 1 is \(1470.3\) and for Group 2 is \(1405.7\)
