Question

In a study to determine the relationship between ambient outdoor temperature and the rate of evaporation of water from soil, measurements of average daytime temperature in °C and evaporation in millimetres per day were taken for 10 days. The results are shown in the following table.  

Temperature Evaporation
11.9 2.4
21.5 4.8
16.5 5.0
23.6 4.1
19.1 6.2
21.6 5.9
31.3 4.8
18.9 3.0
24.2 7.3
19.3 1.6

Test H0β1 = 0 versus H1β1 ≠ 0. Can you conclude that temperature is useful in predicting evaporation? Use the α = 0.01 level of significance.
