Suppose an economics program is interested in determining the average number of students who go on to a graduate program. From the same grade, they take a sample of 35 students and a sample of 75 students. Which of these two samples would be expect to have a smaller margin of error? They should have the same margin of error The first because there are fewer students in the sample The second because the number of students is greater in that sample We need more information to make the determination

Using a confidence interval: We can determine exactly what the population mean is O Determine how confident we are in our regression results The range of possible values for our population mean We get a range of values for that we believe we can find the population means for a given confidence level
