Two ratios that are equivalent to 3:11 are 6:22 and 9:33 :)

Just time both numbers by the times you want, then you will get equivalent ratios. 3:11, 3x2=6, 11x2=22, so the equivalent ratio will be 6:22! In this case, you can get every other euivalent ratio!
Hope that helps you! :)

Step-by-step explanation:

total size of sample = 10,000

                                     men                            women

voted                           2777                            3466

did not vote                  1444                             2313

By chi square test we can find the relationship between gender and participation in the election

<em>X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}</em>

where

a represent  = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

<em>X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}</em>

<em>X^2 = = 35.159</em>

HENCE REQUIRED TEST STATICS IS 35.19
