Question: The following sample observations were randomly selected.

X: 5, 3, 6, 3, 4, 4, 6, 8

Y: 13, 15, 7, 12, 13, 11, 9, 5

1. Determine the regression equation.

   	Coefficients	Standard Error	t Stat	P-value	Lower 95%	Upper 95%
   Intercept	19.11976	1.863507	10.26009	5E-05	14.55992	23.6796
   X	-1.74251	0.362856	-4.80222	0.002994	-2.63039	-0.85464

   
   This means that the regression equation is given by
   \[\hat{Y}=19.1198-1.7425X\]
2. Determine the value of Y’ when X is 7.
