One of the major attractions in Yellowstone National Park is the Old Faithful geyser. The scatterplot shows the relationship between x = the duration of the previous eruption (in minutes) and y = the interval of time between eruptions (in minutes). The equation of the regression line relating these variables is = 33.35 + 13.29x. Predict the interval of time between eruptions if the previous eruption lasted 4 minutes. (LT 2.5.1 #1)
answer choices
The predicted y is 86.51 minutes.
The predicted y is 53.16 minutes.
The predicted y is about 90 minutes.
There is no such thing, because that would be an extrapolation.
