Here are the solutions to the questions.

Question II (Plant Growth Experiment)

This problem requires a Two-Way ANOVA to analyze the effects of Grow-light and Plant food on plant growth, as well as their interaction.

Data Summary:

• Number of Grow-light levels (Factor A) = $a = 2$ (I, II)
• Number of Plant food levels (Factor B) = $b = 3$ (A, B, C)
• Number of observations per cell ($n_c$) = 6
• Total number of observations ($N$) = $a \times b \times n_c = 2 \times 3 \times 6 = 36$

Cell Means:
