Question

2) For rare events, counts (even binomial counts for small p) are approximately Poisson. The variance of the Poisson varies as the mean, so the square root of the counts has a stable variance. Regress the square root of the counts (Y) vs the distance from a marijuana plot and test if the slope is non 0 at the 0.01 level. Calculate a 95% prediction bound for the number of animals dead from the rat poison at 7 miles Test if the correlation is 0 at the.01 level a. b. c. Distance 1.5 miles 31 5.65 0.5 62 7.87 2.5 miles 10 3.2 3.5 miles count count) 2.8 Sart Xbar- 2 Ybar= 4.88 5xx= 5 Sxy -8.82 SSE- 1.18

For the 1st column, 3rd row, it should say "Sqrt (count)". Thanks !!
