2. An experiment was carried out to assess the impact of dose of gaseous carbon disulfide on beetle mortality. Computer Output 2 shows the results of a logistic regression predicting beetle mortality rate from log dose of carbon disulfide. (a) Present the fitted logit line. (b) Compute the estimated mortality rate when the log dose of carbon disulfide is equal to 1.8. (c) Compute the estimated odds ratio for the impact of a unit increase in log dose of carbon disulfide on odds of beetle mortality. (d) Compute the 95% confidence interval for the above odds ratio. (e) What can you conclude regarding the impact of log carbon disulfide dose on mortality rate in beetles? (f) Does the logistic regression model adequately describe the data. Present the evidence backing up your conclusion.Output 2: Beetle Mortality The GENMOD Procedure Model Information Data Set WORK.
