Question

select the correct answer. the histograms below show the enrollment numbers of school a and school b over a 5 - year period. which of the following is true regarding the data sets above? a. school as distribution is skewed right and school bs distribution is skewed left. b. school as distribution is skewed left, and school bs distribution is symmetric. c. school as distribution is skewed left, and school bs distribution is skewed right. d. school as distribution is symmetric and school bs distribution is skewed right.

Explanation:

Step1: Analyze School A's distribution

In School A's histogram, the tail of the distribution extends to the left (lower - enrollment values). This indicates a left - skewed distribution as the lower values pull the tail in that direction.

Step2: Analyze School B's distribution

In School B's histogram, the tail of the distribution extends to the right (lower - enrollment values in later years). This indicates a right - skewed distribution as the lower values in later years pull the tail to the right.

Answer:

C. School A's distribution is skewed left, and School B's distribution is skewed right
