Final answer:
Questions about enrollment numbers and customer purchase patterns can be answered with data, while predicting NBA championship winners involves uncertainties beyond mere data analysis.
Correct option is E. What is the purchase pattern(s) of our customers?
Step-by-step explanation:
The questions that can be better answered using data to reach an evidence-based conclusion are: How many students will enroll for an online class in the Spring, and What are the purchase pattern(s) of our customers. These questions can be approached by collecting and analyzing data on past enrollments and customer's buying behavior, respectively. In contrast, predicting who will win the NBA championship involves uncertainty and can't be definitively determined by existing data alone due to the complexity of variables, though data may help form an educated guess.
The term 'data' encompasses the raw numbers and facts collected for reference or analysis to make informed decisions. For instance, a store calculating the average expenditure on produce per visit would be using data to obtain a statistic, which when applied to an entire population, becomes a parameter.
