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  

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
