Tаble 1: Use the аnswer chоices in this tаble tо answer questiоns 5.1, 5.3 and 5.4. Answer choices Name A id B low C age D lwt E race F smoke G ptl H ht I ui J ftv K bwt lbwdataset.dta 5.1. Perform a logistic regression analysis using a purposive selection of covariates (univariate logistic regression analysis) for the low birthweight (low) and list (all) variables that are significant at the relaxed p-value of 0.25. INSTRUCTION - Type the correct LETTER and use the table above answer choices for the variables. Answer only using the Letter provided in the tables and do not write the variable names or labels, otherwise, Blackboard will mark it incorrectly. PLEASE NOTE THAT THE SPACES TO ENTER THE ANSWERS MAY BE RIGHT AT THE BOTTOM. PLEASE BE CAREFUL WHEN ANSWERING AND MAKE SURE THAT THE BLANK SPACES CORRESPOND WITH THE RIGHT QUESTION. FOR EXAMPLE BLANK 1-7 AT THE BOTTOM CORRESPONDS WITH 5.1. ANSWER = a) [BLANK-1], b) [BLANK-2], c) [BLANK-3], d) [BLANK-4], e) [BLANK-5], f) [BLANK-6], g) [BLANK-7] 5.2. Choose the plausible reason for the importance of the cutoff point of 0.25 in the purposive covariate selection method involved in univariate logistic regression. Choose the correct LETTER only A - the relaxed cutoff is more significant than the 0.05 level of significance this making it ideal for the inclusion of variables in the final model B - the relaxed cutoff is less significant than the 0.05 level of significance thus making it ideal for the inclusion of variables in the final model C - the related cutoff allows potential variables that show promise of significance to be included in the final model D - the relaxed cutoff allows for potential variables that do not show promise of significance to be excluded in the final model Answer = [BLANK-8] 5.3. Run a complete or full logistic regression model based on the variables obtained in 5.1. above and indicate which variables are significant at a p-value of 0.05 INSTRUCTION - Type the correct LETTER and use the table above answer choices for the variables. Answer only using the Letter provided in the tables and do not write the variable names or labels, otherwise, Blackboard will mark it incorrectly. ANSWER = a) [BLANK-9], b) [BLANK-10], c) [BLANK-11] 5.4. Run a full logistic regression model and use factors variable analysis for race (i.e. put "i" "." next to race like this i.race. See example below) in your model. Run the model and list the variables that are significant at 0.05 Example: logistic dead age i.race sex accident poison suicide depression INSTRUCTION - For the answer, type the correct LETTER and use the information in table 1 above as your answer choices for the variables. Answer only using the Letter provided in table 1 and do not write the variable names or labels, otherwise, Blackboard will mark it incorrectly. ANSWER = a) [BLANK-12], b) [BLANK-13], c) [BLANK-14], d) [BLANK-15] 5.5. Based on the last model in Question 5.3., interpret the results (focusing on the odds ratios) of variables that are statistically significant at p
