Obtain the required confidence interval for the slope of the population regression line. You may presume that the assumptions for regression inferences are met. Applicants for a particular job, which involves extensive travel in Spanish speaking countries, must take a proficiency test in Spanish. The sample data below were obtained in a study of the relationship between the numbers of years applicants have studied Spanish and their score on the test. The equation of the regression line is The standard error of the estimate is approximately 5.651. Find a 99% confidence interval for the slope of the population regression line that relates test score to number of years of study.
