The result of the Levene test gives a p value of 0.9978. The p value is greater than the 0.05
significance level. The p value indicates that there is no significant difference in the variances of
the six time periods.
d)
e)
Based on the one way ANOVA test that was conducted , the F ratio (5, 30) = 5.9648 and the p
value was equal to 0.0006. The p value is lower than the 0.05 significance level. We thus reject
the null hypothesis and conclude that there is sufficient evidence that there is a difference in the
percentage of successfully metamorphosed larvae over the six time periods.
f)
Based on the paired student’s t test, the times that are significantly different are only times z...
