Wynn conducts an experiment to investigate the rate of photosynthkfi0g a,r*a ae9tk/ ,kesis, w( q v8br :afooy.8x4p(dxf 8smeasured by oxygen production (mL), of an algae species over t.:(fqfr 88sao xov4 p(ywx8bd ime. Wynn puts six pieces of the algae in six different tubes filled with water and places them at the same distance from the light source. A sample of the oxygen production readings of these tubes after some time are shown in the table below.
1. 1. Find the line of regression equation for the oxygen production, P , in terms of minutes exposed to the light, t .
2. Interpret your model in the context of this question.
2. 1. Find the coefficient of determination, $r^{2}$ . $r^{2}$ ≈
2. Interpret the $r^{2}$ in the context of this question.
3. Use the model found in part $(a)$ to predict the oxygen produced after 25 minutes exposed to the light. ≈ mL
