4) 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 millimeters per day were taken for 10 days. The results are show below: Temperature 11.8 21.5 16.5 23.6 19.1 21.6 31.0 18.9 24.2 19.1 Evaporation 2.4 4.4 5.0 4.1 6.0 5.9 4.8 3.0 7.1 1.6 a) Use Statdisk to find the linear regression line equation. 3 b) Check scatter plot for any non-linear pattern or outliers
