Applicants for a particular job, which involves extensive
travel in Spanish-speaking countries, must take a proficiency test
in Spanish. The sample data were obtained in a study of the
relationship between the numbers of years (x) applicants have
studied Spanish and their score (y) on the test. Use the analysis
to find a 99% confidence interval for the true slope.

A collection of paired data consists of the number of
years that students have studied Spanish and their scores on a
Spanish language proficiency test. A computer program was used to
obtain the least squares linear regression line and the computer
output is shown below. Along with the paired sample data, the
program was also given an x value of 2 (years of study) to be used
for predicting test score.
