A study was carried out in n = 6 small apple orchards. The i - th orchard has r; trees which were all given a dose of additive x₁. After one month, yi, the number of trees that did not have certain fungus was recorded. The following is the data per orchard, presented in the format (ri, yi, x₁): (25,18,-1), (40,22,-0.6), (35,15,-0.2), (45,22,0.2), (35,13,0.6), (20,7,1). In this problem, the values of doses of additive are coded, hence the negative x; values. The following are outputs from the analysis of these data after fitting a glm model with logit link and binomial distribution. Bo = -0.0824, B₁ = -0.6622 The null deviance was 10.1378 on 5 degrees of freedom. 2.2259 of freedom
