Given the following bivariate data

x	11	15	19	23	27
y	150	270	450	580	740

1. Find SS _xx =

2. Find SS _yy =

3. Find SS _xy =

4. Find the coefficient of correlation between x and y

r =

5. Find the equation of the regression model

ŷ = ()x +()

6. What is the predicted value ŷ of x= 20?

ŷ _p =

7. Find The sum squares error SSE =

8. Find the standard error SE =

9. At α = .05, test whether the slope B1 of the population regression line is different from zero. That is Ho: B1 =0 vs Ha: B1 ≠ 0

( write either reject H _o or accept H _o )
