Tomato Plants and Colored Light Jennifer Brogan, a biology student who was taking a statistics class, exposed similar tomato plants to different colors of light. The average growth rates (in millimeters per week) are given in the table.
a. Interpret the boxplots given. Compare medians and interquartile ranges, and mention potential outliers.
b. Test the hypothesis that the color of light affects growth rate - in other words, that the population mean growth rates differ by color - reporting the F-statistic, p-value, and conclusion. Assume that conditions for ANOVA are met. Use a significance level of 0.05. Do not do post-hoc tests.
