Confidence intervals for the y-intercept of a regression line (y = (30 + /3,x) can be found

Question:

Confidence intervals for the y-intercept of a regression line (y = (30 + /3,x) can be found by evaluating the limits in the intervals below:
Confidence intervals for the y-intercept of a regression line (y

In these expressions, the y-intercept b0 is found from the sample data and t a/2 is found from Table A-3 by using n - 2 degrees of freedom. Using the earthquake data in Table 11-1, find the 95% confidence interval estimates of β0.
