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 independent (x) variable. Find the best predicted time of the interval after an eruption given that the current eruption has a height of 72 feet. Use a significance level of 0.05.

Height (ft) 128 129 82 95 99 91 122 106
Interval after (min) 79 84 90 62 69 84 66 86

What is the regression equation?
Ŷ = 85.54 -.0755x (Round to three decimal places as needed.)

What is the best predicted value?
Ŷ(72) = 80.104 = 80 min 6 sec Minutes (Round to one decimal place as needed.)
