1.A researcher is interested in how plants respond to the environment. To study these differences, they randomly assign 60 plants to one of three groups: an auditorily-enriched environment (n=20), a visually-enriched environment (n=20), and a 'typical' environment (n=20). They then measure their growth after six months. In order to find out if there were differences in average growth after six months, they conduct an ANOVA using an alpha level of 0.05.

The SS between for the analysis was 403.2, and the SS within was 407.8.

Can you fill in the rest of the ANOVA table for them using the above information, and then figure out if there was a significant difference between groups (said another way, would you reject the null)? Make sure your show your work for the following items:
