a. description

Step-by-step explanation:

Description statistics is used to summarize sample or population by determining some of its parameters like mean, variance, standard deviation, proportion etc.

Stacy Wood at the Moore School of Business in South Carolina studied her samples and find sample proportions of a specific characteristic (proportion of people who chose new item) from two different samples of people who are identifying themselfves in a period of change and people who are not)

For example, if she further continues the study and finds with 95% confidence that proportion of people who are in a perid of change choses new item are higher than the proportion of people who are not in a period of change, then she would have made inferential statistics.
