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. Describe the scatterplot.

Select one:

a.There is a positive, linear relationship between the variables.

b.As the duration of each eruption increases, the time between eruptions decreases.

c.The scatterplot is skewed right with many outliers.

d.There is a negative, linear relationship between the variables.
