Yellоwstоne Nаtiоnаl Pаrk in Wyoming has a famous hot spring which erupts hot water and steam into the air. There appears to be a linear relationship between the variable y measuring the waiting time until the next eruption and the variable x measuring the duration of an eruption. A park ranger collected some data, measuring both variables in minutes, and calculated that the prediction equation is given by y = 45.6 + 9.7x. She also found that the correlation coefficient of the two variables is 0.84 and the coefficient of determination is approximately 0.71. Predict the waiting time (y) until the next eruption if the last eruption lasted for [x] minutes.
