Question

A random sample of 35 two-year colleges in 2008–2009 collected data on the in-state tuition costs and enrollment totals. Based on the sample, the researchers estimated the mean in-state tuition for all two-year colleges to be $2,380. Which form of statistical inference does this conclusion represent? Hypothesis testing Point estimation Interval estimation

Answer 1

Explanation:

In this research, the mean tuition for a random sample of the population of all two-year colleges ($2,380) was considered the mean tuition for all two-year colleges in the state. This practice of estimating a parameter of a population through a single value obtained from a sample data is known as Point estimation.
