Using the contingency table below, complete the table, and then calculate the expected counts for AIDS yes/male, AIDS yes/female, AIDS no/male, AIDS no/female.
| Sex | |||
| AIDS | Male | Female | Total |
| Yes | 40 | 20 | 60 |
| No | 30 | 160 | 190 |
| Total | 70 | 180 | ? |
Solution
TOTAL = 190+60 = 250
PROBABILITY OF YES AIDS GIVEN ITS MALE WILL BE 40/70 AS TOTAL MALE = 70 AN YES WILL BE 40
PROBABILITY OF AIDS YES GIVEN ITS FEMALE WILL BE 20/180 AS TOTAL FEMALE = 180 ANS YES ARE 20
PROBABILITY OF AIDS NO GIVEN ITS MALE = 30/70 AS TOTAL MALE = 70 AND MALE WITH NO AIDS = 30
PROBABILITY OF AIDS NO GIVEN ITS FEMALE = 160/180 AS TOTAL FEMALE = 180 AND WITH NO AIDS =160
