Construct the 95 confidence interval for the slope coefficie
Construct the 95% confidence interval for the slope coefficient. (Negative values should be indicated by a minus sign. Round your intermediate calculations to 4 decimal places,\"t/2,df\" value to 3 decimal places and final answers to 2 decimal places.)
At the 5% significance level, does the slope differ from zero?
| Consider the following simple linear regression results based on 20 observations. Use Table 2. |
Solution
a1) H0: 0 = 0; HA: 0 0
a2) Reject H0Picture the intercept differs from zero.
b1) (0.06 , 0.44 )
b2) No because 0 is in this CI.
