A sample 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 are used for a chi-square test for independence, what is the total number of females for the expected frequencies

Chi - square test is a test of whether two variables are independent or not,

In 80 females, there are 48 females are registered voter and 32 female are non registered voters.

Since, The sample consists of 80 females and 20 males, and has a total of 60 registered voters.

80

Step-by-step explanation:

Using this as a guide,

Number of Registered voters = 60

Number of non registered voters = 40

Total number of women in sample is 80

Total number of men in sample is 20

Thus, the expected frequencies for female registered voters

= (80/100)*60

= 48

Expected frequency for female non registered voters is

= (80/100)*40

= 32

Therefore, the total number of females for the expected frequencies is

48+32 = 80
