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 105 feet. Use a significance level of 0.05. What is the regression equation? y cap = + x (Round to two decimal places as needed.) What is the best predicted value? y cap approx minutes (Round to one decimal place as needed.)

Solution

Using technology to get the coefficients,

y^ = 17.22 + 0.52x [ANSWER]

*******************

Evaluating y^ at x = 105,

y^(105) = 71.9 [ANSWER]
