Consider the following data on x = rainfall volume (m³) and y = runoff volume (m³) for a particular location.
x 4 12 14 17 23 30 40 52 55 67 72 79 96 112 127
y 4 10 13 15 15 25 27 45 38 46 53 74 82 99 105
Use the accompanying Minitab output to decide whether there is a useful linear relationship between rainfall and runoff.
O Ho: P₁0
H₂: B₁ <0
OH:₁0
H₂: P₁ = 0
O Ho: P₁ = 0
Ha: P₁ #0
The regression equation is

State the conclusion in the problem context. (Use a = 0.05.)
O Reject H. There is a useful linear relationship between runoff and rainfall at the 0.05 level.
O Reject Ho. There is not a useful linear relationship between runoff and rainfall at the 0.05 level.
O Fail to reject Ho. There is not a useful linear relationship between runoff and rainfall at the 0.05 level.
O Fail to reject H. There is a useful linear relationship between runoff and rainfall at the 0.05 level.
Calculate a 95% confidence interval for the true average change in runoff volume associated with a 1 m² increase in rainfall volume. (Round your answers to three decimal places.)
