Question

A polling company wants to know how voters' age affect their voting for a candidate. The sample data is in the following

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

Ans a ) the binary logistic regression equation is

p(voting ) = 0.046*Age -1.341

b ) for age = 54

p(voting ) = 0.046*54 -1.341

p(voting )= 1

c ) since p value of age is less than 0.05 so we conclude that age has not significant effect on voting

Answer 2

Solubon @ Binary logistic Regression equabón is log () = Bot Bet at Bp xp Log(, -1.341 +0.046 (age) pro babi'iity voting candidate for T is 1 - A+Bex, Ite that ܘ 54 years for the candiate probability voter will vote is T and is TI - (-1341 +0.046154) 1+ e TT 0.7582 ③ we ue wait test for testing voting at 2 -0.05 Sibenificant effect on 0 VS HI: Page to Ho page W = ß² varlß) NX,? 2 0.046 4.123 ~ X,2 60.00) 0.022 i's 0.041 p-value

p-value less than 2005 So Reject Ho Ho page O le, There is significant on effects age voting like. Thank give me please you.
