Four different types of insecticides are used on strawberry plants. The number of strawberries on eachrandomly selected plant is given below. Find the test statistic F to test the hypothesis that the type of insecticidemakes no difference in the mean number of strawberries per plant. Use α = 0.01. $$\begin{array} { c c c c }
\hline \text { Insecticide } 1 & \text { Insecticide } 2 & \text { Insecticide } 3 & \text { Insecticide } 4 \
\hline 6 & 5 & 6 & 3 \
5 & 8 & 3 & 5 \
6 & 5 & 4 & 3 \
7 & 5 & 3 & 4 \
7 & 5 & 2 & 5 \
6 & 6 & 3 & 4 \

Quizplus · Accepted Answer

The test statistic F is calculated using ANOVA (Analysis of Variance) to compare the means of the four groups. Given the data, the correct calculation results in an F value of 8.357, indicating the variance between the groups relative to the variance within the groups.
