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 tie of the interval after an eruption given that the current eruption has a height of 84 feet. Use a significant level of 0.05.
A. What is the regression equation? Ŷ = __ + ___x
B. What is the best predicted value? Ŷ ͌ __ minutes
