Question

A student organization wondered how many hours per week college students study during a term. The organization obtained a list of all students at their university and randomly selected 100 from the list. They contacted all 100 students and all 100 provided their best estimate of the number of hours they typically study per week. A​ 95% confidence interval for the mean number of hours studied per week was constructed. Based on this​ study, to what population can we make an inference using the confidence​ interval?

Answer 1

Given that the student organization want to estimate mean number of hours per week college student study during exam. They find the 95% confidence interval for the mean number of hours per week college student study during exam from a random sample of 100 obtained from their University.

Therefore the population for which we make inference using the confidence interval is the number of hours week college student study in the give University.

Since random samples are selected from this university.
