Homework Help - October 2006

(Okay I have another question that I am just stuck on... I read my book but it doesn't explain how to do this.)

Calculate the standard deviations for test scores and interview scores as well. Using a t-test for the difference in the mean, would you conclude that the mean test score for hires is significantly higher (at the 10% level of confidence) than the test score for non-hires? Is the mean interview score for hires significantly higher for hires than for non-hires?

The mean score for all interview scores is 71.5, the mean score for all test taking is 56.25. The mean interview score for hires is 74.5 and the mean test score was 58.75. The mean score for interview for non-hires is 61.5 and test score is 45.
