[填空题]
Wynn conducts an exp)ph torcodp6(9) msz;7)tkcvlix 6c ) qcqp*9t8 e0kqytj-7veriment to investigate the rate of photosynthesis, measured by oxygen production (mL), of an algae species over time. Wynn puts six pieces of tt)x9 l k07qpy kv6ec-icj)*tv8qq7t che 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
