Explanation:

Descriptive statistics summarize or visualize existing, complete data sets, rather than inferring about a larger population.

1. Sampling voters to predict an election uses sample data to infer about the entire voter population, which is inferential statistics, not descriptive.
2. A pie chart showing class majors summarizes data from the specific class (a complete set for that group), so this is descriptive statistics.
3. Checking 4 stores to estimate the average camera price uses a sample to infer the overall average, which is inferential statistics.
4. Calculating summary measures for all houses sold in Las Vegas in January summarizes a complete, specific data set, so this is descriptive statistics.

Answer:

B. Creating a pie chart to show majors of students in your business statistics class.
D. Calculating summary measures of the prices of houses sold in Las Vegas in January.
