A local business school claims that its graduating seniors get higher-paying jobs than the national average for business school graduates. Last year's figures for salaries paid to all business school graduates on their first job showed a mean of $10.20 per hour. A random sample of 10 graduates from last year's class of the local business school showed the following hourly salaries for their first job: $9.40, $10.30, $11.20, $10.80, $10.40, $9.70, $9.80, $10.60, $10.70, $10.90. You are skeptical of the business school's claim and decide to evaluate the salary of the business school graduates using a 2-tail test with ? = 0.05. What do you conclude?
