Question

Can we predict the next eruption of the Old Faithful geyser by knowing the duration of the previous eruption? The observations and least squares regression line appear in the scatterplot. The scatterplot and the least-squares regression line for predicting the Interval (minutes) between eruptions and the Duration (minutes) of the previous eruption is given below. Which of the following is the correct interpretation of the slope of the least squares regression line for the data about Old Faithful?

Answer 1

The correct answer is We can predict the time between eruptions will be 10.73 minutes and this can be stated with 0.901 probability.

Eruptions do not always produce symmetrical and imposing cones. Volcanic relief has varied shapes and we must analyze the properties of the lava and the conditions of spill occurrence to understand.
