Suppose that a study is conducted to determine if environmental aspects and feed type impact the growth of chickens, specifically their weight over time. An ANOVA procedure is conducted and the following table results: Source feed type environment Residuals Sum of Squares 231129 24 195532 DF 5 1 64 Mean Squares 46226 24 3055 F-statistic 15.13 0.0079 To determine if there a significant effect on a chicks weight due to their environment, an F-test on the variable “environment” is conducted. Is the main effect of “environment” significant at the 0.05 significance level? Yes, since the F-statistic is less than 0.05 Yes, since the p-value associated with the F-statistic for "environment" is less than 0.05. No, since the p-value associated with the F-statistic for "environment" is greater than 0.05.

Question
Suppose that a study is conducted to determine if environmental aspects and feed type impact the growth of chickens, specifically their weight over time. An ANOVA procedure is conducted and the following table results:
| Source feed type environment Residuals |
Sum of Squares 231129 24 195532 |
DF 5 1 64 |
Mean Squares 46226 24 3055 |
F-statistic 15.13 0.0079 |
To determine if there a significant effect on a chicks weight due to their environment, an F-test on the variable “environment” is conducted. Is the main effect of “environment” significant at the 0.05 significance level?
Yes, since the F-statistic is less than 0.05
Yes, since the p-value associated with the F-statistic for "environment" is less than 0.05.
No, since the p-value associated with the F-statistic for "environment" is greater than 0.05.
