Exp(B) Age .046 .022 4.173 1 .041 1.047 Step 1° Constant - 1.341 .872 2.367 1 .124 .262 a. Variable(s) entered on step 1: Age. (a) Find the binary logistic regression equation. (b) Find the probability that a 54 years old voter will vote for the candidate. (c) At a = 0.05, determine whether there is evidence that age has significant effect on voting,

Answer 1

a Binary Logistic Regression equation is given, Log (177) Potpix, t... Fpt up Here Log (11) G----):341 +0.046 (32) It is probability for voting candidate. It = It et effiXT b] prob. that a 54 year old voter will vote for the candidate is denoted by T & given by c] JT Ite (1.341 +0.046254) - 0.7581 We use Walt test for testing significant effect on Voting at Ho: Page=0 vs HE BAge to Nx? vares) 0.046 4.173 ou x² x = 0.05 82 1) = 0.022 P value is 0.041 which is less that 2=0.05 so we Reject Ho: Page=o je there is significantly Age effects on voting
