Question: During 2008, college work-study students earned a mean of $1478. Assume that a sample consisting of 45 of the work-study students at a large university

During 2008, college work-study students earned a mean of $1478. Assume that a sample consisting of 45 of the work-study students at a large university was found to have earned a mean of $1503 during that year, with a standard deviation of $210. Would a one-tail test at the 0.05 level suggest the average earnings of this university’s work-study students were significantly higher than the national mean?
