Based on a sample of twenty-five observations, the population regression model was estimated. The least squares estimates obtained were a-15.6 and The total and error sums of squares were SST = 268 and b=1.3 SSE = 204

(a) Find and interpret the coefficient of determination.

(b) Test against a two-sided alterative at the 5% significance level the null hypothesis that the slope of the population regression line is 0.

(c) Find a 95% confidence interval for B.
