QUESTION 6 SHSU would like to construct a confidence interval for the difference in salaries for business professors (group 1) and criminal justice professors (group 2). The university randomly selects a sample of 47 business professors and finds their average salary to be $84198. The university also selects a random sample of 63 criminal justice professors and finds their average salary is $63048. The population standard deviations are known and equal to $9000 for business professors, respectively $7500 for criminal justice professors. The university wants to estimate the difference in salaries between the two groups by constructing a 95% confidence interval. Compute the upper confidence limit. Round your answer to 2 decimals, if needed.
