[填空题]
Wynn conducts an experiment to investigate thu*co2nybl h4e5(a8u w e rate o39fwd 5dbd 7rxi ko*r*f photosynthesis, measured by oxygen production (mL), of an algae species over time. 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 p of xki73dwd9*brd *5rroduction 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
