"Factors Influencing the Total Mercury and Methyl Mercury in the Hair of Fishermen in Kuwait," Environmental Pollution, Vol. 109, pp. 239-250 Description: Factors related to mercury levels among fishermen and a control group of non-fishermen. Variablesames Fisherman indicator (fisherman) Age in years (age) Residence Time in years (restime) Height in cm (height) Weight in kg (weight) Fish meals per week ((fishmlwk) Parts of fish consumed: 0=none, 1=muscle tissue only, 2=mt and sometimes whole fish, 3=whole fish (fishpart) Methyl Mercury in mg/g (MeHg) Total Mercury in mg/g (TotHg)\fUsing backward elimination, which of the five variables is the first eliminated? O No variable is eliminated at the first run O age O weight O height O fishmlwk O restimeIndicate the p-value of the first eliminated variable, rounded off to ONLY FOUR decimal places. If no variable is eliminated at first run, write O.Using backward elimination, which of the four remaining variables is the second eliminated? O age O height O restime O fishmlwk O No variable is eliminated at the second run O weightIndicate the p-value of the second eliminated variable. rounded off to ONLY FOUR decimal places. If no variable is eliminated at second run, write 0.Using backward elimination, which of the 3 remaining variables is the third eliminated? O fishmlwk O weight O height O age O restime O No variable is eliminated at the third runIndicate the p-value of the 3rd eliminated variable, rounded off to ONLY FOUR decimal places. If no variable is eliminated at 3rd run, write O.Using backward elimination, which is the fifth and final variable eliminated? O restime O height O fishmlwk O age O weight O No variable is eliminated at the fifth and final runIndicate the p-value of the 5th and final eliminated variable. rounded off to ONLY FOUR decimal places. If no variable is eliminated at 5th and final run, write O.Indicate the R value of the FINAL multiple linear regression model, rounded off to only.r FOUR decimal places Indicate the R^2 value of the FINAL multiple linear regression model, rounded off to only FOUR decimal placesGiven the final model, indicate the predicted Tothe value of the 22nd sample unit, rounded off to only FOUR decimal places.Given the final model, indicate the residual value of the 35th sample unit, rounded off to only FOUR decimal places.\fGiven the final model, what is the RMSE value?What is the Kolmogorov-Smirnov test statistic value for the residuals of the final model, rounded off to only FOUR decimal places?What can you say about the scatterplot of the residuals and DV values from the final model? O Not funnel-shaped, indicative of non-constancy in variance O Funnel-shaped, indicative of non-constancy in variance O Funnel-shaped, indicative of constancy in variance O Not funnel-shaped, indicative of constancy in varianceWhat is the tolerance value from the final model, rounded off to only 4 decimal places?What is the largest Cook's distance value from the final model, rounded off to only four decimal places
