The data show the time intervals after an eruption (to the
next eruption) of a certain geyser. Find the regression equation,
letting the height of the current eruption be the explanatory
variable (denoted by x). Then use this equation to determine the
predicted length of the time interval after an eruption given that
the current eruption has a height of 113feet.
