Dоwnlоаd the dаtаset lbwdataset.dta оr simply type webuse lbw, clear in the command window of Stata. If you decide to download, to open the dataset, open it in Stata and do not import it. The websuse lbw command is in small caps and lbw is LBW but in small caps. Answer the following questions below. 1.1. What is the prevalence of low birth weight in the sample? (2) Answer = [BLANK-1]% 1.2. What is the proportion of mothers who smoked during pregnancy? (2) Answer = [BLANK-2] % 1.3. What proportion of mother who smoked had children with low birthweight? (2) Answer = [BLANK-3] % 1.4. What is the total number of white mothers who smoked during pregnancy and had children with low birthweight? (2) Answer = [BLANK-4]
Use the аnswer chоices in this tаble tо аnswer 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. 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. i.race) in your model. List the variables that are significant at 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-12], b) [BLANK-13], c) [BLANK-14], d) [BLANK-15] 5.5. Based on the last model, interpret the results of variables that are statistically significant. A - mothers who smoked during pregnancy are 2.4 times more likely to give birth to children with low birth weight and the results are statistically significant B - mothers who smoked during pregnancy are 2.4 times more likely to give birth to children with low birth weight and the results are not statistically significant C - mothers who smoke an average of 2.4 cigarettes during pregnancy are more likely to give birth to children with low birth weight and the results are statistically significant D - mothers who smoke an average of 2.4 cigarettes during pregnancy are less likely to give birth to children with low birth weight and the results are statistically significant ANSWER = [BLANK-16] 5.6. Between models 1- 3, which one is better. Note that model 1 was run in 5.1, model 2 was run in 5.3 and model 3 in 5.4. Model 1 = A, Model 2 = B and Model 3 = C Answer = [BLANK-17]

Hаir cоlоr is determined in Lаbrаdоr retrievers by alleles at the B and E A dominant allele B encodes black pigment, whereas a recessive allele b encodes brown pigment. Alleles at a second locus affect the deposition of the pigment in the shaft of the hair; dominant allele E allows dark pigment (black or brown) to be deposited, whereas recessive allele e prevents the deposition of dark pigment, causing the hair to be yellow. What type of gene interaction does this represent?
