Answer: B. Population X will require a larger sample size

Step-by-step explanation:

If a random variable say p has skewed distribution (whether right or left) in a population then a bigger sample size is needed to make sure that the sampling distribution follows normal distribution.

Given : Two population distributions labeled X and Y.

Distribution X → highly skewed

Distribution Y → slightly skewed.

Since Distribution X more skewed so, we will need a larger sample size of population X as compared to Y.

Hence, the correct answer is B. Population X will require a larger sample size
