Question

What test will you use to look for an effect of predators on how much the bunnies eat saplings? Data Set #3 While investigating habitat use by cottontail rabbits, you decide to evaluate the impact of rabbit browsing on tree sapling growth. To accomplish this, you set up seven exclusion areas ('no predator) using rabbit-proof fencing and seven non-exclusion areas of equal size with no fencing (predator"). After two years you compare the mean tree sapling height (cm) from the "no predator" and "predator" treatments No Predator 218.3 224.8 244.09 230,T 211.33 250.2 234.95 Predator 52.07 25.91 39.88 46.8 35.7 64.2 594 t-test ANOVA Regression Ch square

Explanation / Answer

as we compare the mean rate between two diffrence data values this should be t test diffrence of mean for which data is independently selecetd.

and we set up the test as following,

null, Ho: u1 - u2 =0
alternate, H1: u1 - u2 <>0
we use test statistic (t) = (x-y)/sqrt(s.d1^2/n1)+(s.d2^2/n2)
