There is a linear relationship between the duration x (in seconds) of an eruption of a geyser and the interval of time y (in minutes) until the next eruption. A least-squares regression line of data collected by a geologist is represented by, y-hat=41.9=0.18x, 100<x<300. What is the estimated increase in the interval of time until the next wruption that corresponds to an increase of 60 seconds in the duration?
