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?

select one:

a. we can predict the time between eruptions will be 10.73 minutes and this can be stated with 0.901 probability.

b. if duration goes up by one minute, then the interval between eruptions increases by 10.73 minutes on the average.

c. the slope indicates that the correlation should be negative.

d. the time between eruptions increases by about 33.47 minutes on the average.
