Explanation / Answer

1) according to the question we have to find the claim that the women percentage is higher in older age group then other according to this option d is correct.

2) the method best will be to compare the conditional distribution of each gender hence option A is correct.

c) for 18 - 24

total students = 12072

total females = 6432

hence percentage = 6472/12072 = 53.28% hence 4 for this

for 25 to 34

total students = 4293

total females = 2450

percentage = 2450/4293 = 57.07% = 10th option

for 35 to older

total student = 3193

female = 2124

percentage = 2124/3193 = 66.5% = 1st option

4) based on the result the conclusion will be that the women in 1st group has less majority'hence option A is correct.
