Making Predictions. In Exercises 58, let the predictor variable x be the first variablegiven. Use the given data to find the regression equation and the best predicted value ofthe response variable. Be sure to follow the prediction procedure summarized in Figure10-5. Old Faithful For 40 eruptions of the Old Faithful geyser in Yellowstone National Park,duration times (sec) were recorded along with the heights (ft) of the eruptions. The linear correlationcoefficient is r = 0.0915 and the regression equation is ny = 119 + 0.0331x, wherex represents duration time. The mean of the 40 duration times is 245.0 sec and the mean ofthe 40 heights is 127.2 ft. What is the best predicted height of an eruption with a durationtime of 120 min?
