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

Sloan [31]

Answer:

P \cap R=\{2,3,5,7\}

Step-by-step explanation:

Given : Let P={ 1,2,3,5,7,9}, Q= { 1,2,3,4,5}, and R= {2,3,5,7,11}

Solution :

The intersection of two sets is defined as the set of their common elements or the elements appear in both the sets.

The sets are P={ 1,2,3,5,7,9} and R= {2,3,5,7,11}

Common elements in P and R are {2,3,5,7}

So, P \cap R=\{2,3,5,7\}

Therefore, The value of P \cap R=\{2,3,5,7\}
