a significant trendP = 0.01
There is a significant trend (P = 0.01) in which cuticle thickness generally increases with increasing length of time to knock-down, although the correlation is weak (R 2 = 0.33).
There is a significant trend (P = 0.01) in which cuticle thickness generally increases with increasing length of time to knock-down, although the correlation is weak (R 2 = 0.33).
The permethrin tolerant and intolerant groups were then compared using one-way ANOVA and a possible trend between cuticle thickness and time to knock-down was evaluated using linear regression (Statistix 7.0 software).
