The data show the time intervals after an eruption (to the next eruption) of a certain geyser. Find the regression equation , letting the first variable be the independent (x) variable. Find the best predicted time of the interval after an eruption given that the current eruption has a height of 70 ft. Use a significance level of 0.05. Please show all your work.
