Answer:
To calculate the joint frequency of female and male voters for Candidate Smith, we need to add the frequency of female voters who chose Smith (300) with the frequency of male voters who chose Smith (400), which gives us a total of 700.
Then, we divide this total by the total number of voters (300 + 400 + 200 + 600 = 1500) to get the joint frequency for Candidate Smith:
Female voters who chose Smith: 300
Male voters who chose Smith: 400
Total voters who chose Smith: 700
Joint frequency for Candidate Smith = (300 + 400) / 1500 = 0.5
Therefore, the joint frequency for female and male voters who chose Candidate Smith is 0.5.
