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

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
