Final answer:
Without specific data or a reliable source, the correct number of incoming freshmen in Fall 2018 cannot be confirmed; thus, the answer is D) None of the above. For after-school sports participation by seniors, binomial distribution could provide insight, but numerical data is required for a justified answer.
Step-by-step explanation:
To answer the question about the number of incoming freshmen in Fall 2018, we need to reference specific data from a reliable source. Unfortunately, without additional context or a specified institution, it is impossible to determine the exact number of incoming freshmen from the multiple-choice options provided. Each college or university will have different enrolment numbers. Therefore, based on the information given, the answer is D) None of the above, as we cannot confirm the correct number of incoming freshmen without the proper data source.
Regarding the participation in after-school sports by seniors, if we had numerical data indicating the likelihood or percentage of engagement over the four years at high school, we could use binomial distribution analysis to predict the probability of any given number of seniors participating in sports throughout their high school career. However, without that data, we cannot make a justified numerical determination.
