Solution by Steps

step 1

To determine which major has a mean SAT score greater than the median, we look at the shape of the distribution

step 2

A right-skewed distribution typically has a mean that is greater than the median

step 3

The Anthropology major's distribution is right-skewed, indicating that the mean is greater than the median for Anthropology

step 4

To determine which major has a greater median SAT score, we compare the center values of the distributions

step 5

The Economics major's distribution is more symmetrical, suggesting that the median is near the center of the distribution

step 6

Since the Economics distribution is centered higher on the SAT score scale than the Anthropology distribution, Economics has a greater median SAT score

[question 1] Answer

For Anthropology majors, the mean SAT score is greater than the median.
The Economics majors have a greater median SAT score.

Key Concept

Distribution Shape and Central Tendencies

Explanation

The shape of a distribution can indicate the relationship between the mean and median. A right-skewed distribution typically has a mean greater than the median, while a symmetrical distribution suggests the mean and median are close. The median is the middle value, so for a symmetrical distribution centered higher on the scale, the median will be higher.
