Question

In the 1990's about 75% of high school graduates attended college. A survey of 2,000 high school graduates was taken in 2018 that showed 1,453 attended college. Do these responses provide strong evidence that the 75% figure is not accurate for current graduates? State the hypothesis and your conclusion using statistical evidence. What does your conclusion mean in context?

Answer 1

These responses do show strong evidence that the 75% figure is accurate for current high school graduates going off to attend college

Explanation:

1453/2000 = .7265 or 72.65%

If 1,453 students of a 2,000 student high school attend college after high school, than 72.65% of the students in the high school on average will attend college after they graduate. This percentage compared to the 1990's are a mere 2.35% behind the 75% mark. In this example that is the difference between 1,453 students and 1,500 students. Since these percentages are relatively similar, a conclusion could be made that the 75% mark is an accurate average representation of how many high school graduates will attend college in the future.
