Asample of 100 people is classified by gender (male/female) and by whether they are registered voters. the sample consists of 80 females and 20 males, and has a total of 60 registered voters. if these data were used for a chi-square test for independence, what is the expected frequency for males who are registered voters?

12

Step-by-step explanation:

Given :

                                    Male         Female        Total

Registered                                                          60

Non registered                                                   40

Total                          20                  80    

Solution :

N= 100

Formula of expected frequency =

= expected frequency for the ith row/jth columm.

= total in the ith row

= total in the jth column

N = table grand total.

So, using formula  

Expected frequency table

                                    Male         Female        Total

Registered                  12                  48            60

Non registered           8                   32             40

Total                           20                  80    

So, the expected frequency for males who are registered voters are
