c. The percentage of females in the sample

Step-by-step explanation:

Total high school student = 347.

There are 95 liberals of which 27 are males and 68 are females.

Of 128 Moderates, 91 are females and males are 37 in number

To find the total number of conservatives, we have:

  Total no - (total moderates + total liberals) = total conservatives

   347 - (128 + 95)

    347 - 223

   = 124 number of conservatives of which females are 93 and males are 31.

a. The joint frequency for liberal females is 68

b. And the largest marginal frequency for political preference is 128 moderates

c. what does the relative frequency 252/347 represent?

total females: 68 + 91 + 93 = 252 out of 347 students. The percentage of females in the sample
