A certain chemical process is run 10 times at a temperature of 65°C and 10 times at atemperature of 80°C. The yield at each run was measured as a percent of a theoreticalmaximum. The data are presented in the following table.65° C 71.3 69.1 70.3 69.9 71.1 70.7 69.8 68.5 70.9 69.8190.3 90.8 91.2 90.7 89.0 89.7 91.3 91.2 89.7 91.180° CFor each temperature, estimate the mean yield and find the uncertainty in the estimate.b. Estimate the difference between the mean yields at the two temperatures, and find theuncertainty in the estimate.a.

To determine: Estimate the mean yield and the uncertainty in the estimate of each temperature. To…

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)]…
