In a study to determine the relationship between ambient outdoor temperature and the rateof evaporation of water from soil, measurements of average daytime temperature in °C andevaporation in mm/day were taken for 40 days. The results are shown in the following table.Temp.Evap.11.82.421.54.416.55.023.64.16.019.121.65.931.04.818.93.024.27.119.11.611.83.8 24.25.015.82.626.88.024.85.426.24.214.214.14.42.230.35.715.21.218.63.525.45.522.14.825.44.822.63.224.45.115.83.322.34.923.27.419.73.314.01.113.63.525.45.117.72.024.75.724.34.725.85.828.35.829.87.826.55.1Compute the least-squares line for predicting evaporation (y) from temperature (x).b.

When water flows across farmland, some soil is washed away, resulting in erosion. An experiment was conducted to investigate the effect of the rate of water flow (liters per second) on the amount of soil (kilograms) washed away. The data are given in the following table: Flow rate 0.31 0.85 1.26 2.47 3.75 Eroded soil 0.82 1.95 2.18 3.01 6.07 Let xx represent the flow rate variable and yy represent the variable for soil eroded. Then \bar x = 1.73, s_x = 1.38, \bar y = 2.81, s_y = 1.99xˉ=1.73,sx=1.38,yˉ=2.81,sy=1.99 Use this to complete the following calculation of the correlation coefficient for these data. r = \frac{1}{n-1}\left[\left(\frac{x_1 - \bar x}{s_x}\right)\left(\frac{y_1 - \bar y}{s_y}\right) + \left(\frac{x_2 - \bar x}{s_x}\right)\left(\frac{y_2 - \bar y}{s_y}\right) + \cdots + \left(\frac{x_n - \bar x}{s_x}\right)\left(\frac{y_n - \bar y}{s_y}\right)\right]r=n−11[(sxx1−xˉ)(syy1−yˉ)+(sxx2−xˉ)(syy2−yˉ)+⋯+(sxxn−xˉ)(syyn−yˉ)]…
