Given the simple regression model, Y=Beta0 + beta0 X and the regression results follow, test the null hypothesis that the slope coefficient is 0 versus the alternative hypothesis of greater than 0 using the probability of type 1 error equal to 0,05 and determine the two-sided 95% and 99% confidence intervals.

a) a random sample of size n=38 with b1=5 and Sb1=2.1

b) a random sample of size n=46 with b1=5.2 and Sb1=2.1

c) a random sample of size n=38 with b1=2.7 and Sb1=1.87
