Answer #1

Solution:

We are given that: at the local college, a study found that students completed an average of 4.6 classes per semester.

That is:

Sample size = n= 44

We have to find the best point estimate for the average number of classes per semester for all students at the local college.

Since sample mean is an unbiased estimator of population mean, that is: , That is sample mean is the best point estimate of population mean, thus the sample mean : is the best point estimate for the average number of classes per semester for all students at the local college.

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...
