Fit a logistic regression model logit(P(killedjdose)) = 0 + 1 dose + 2 (dose) 2 : Write the values of the three coe¢ cient estimates here: ^ 0 = ; ^ 1 = : ^ 2= 1.2 Estimate the probability that a beetle exposed to a dose of 0:5 units of the insecticide will not survive. 1.3 Find an approximate 90% conÖdence interval for in Question 1.2. 1.4 Use the Wald statistic to test at the 1% level of signiÖcance whether the estimated coe¢ cient of (dose) 2 is statistically signiÖcant. 1.5 Assess the quality of the Öt. Show one of your diagnostic plots (a rough freehand version will be acceptable) and indicate the relevant features on it that point to a satisfactory or unsatisfactory Öt.
