A study is conducted to determine the simple linear regression relation (if any) between average temperature over a week and ice-cream sales in a particular city. The following table provides the regression data required to construct the model:

Average Temperature and Ice-cream Sales
Average Temperature
over a Week (°F)
Weekly Ice-cream Sales
($'000s)
75 320.196
63 277.912
64 280.789
45 213.996
66 288.003
83 348.772
74 316.879
47 221.67
42 204.195
73 313.072
50 232.421
50 231.301

Calculate the slope (b1) and intercept (b0) of the simple regression equation using the data provided. Give your answers to 2 decimal places.

(a)Slope = b1 =

(b)Intercept = b0 =
