Question description

  1. In tough economic times, people are asked to do more with less money. Schools have been on the receiving end of budget cuts. Have those cuts affected the graduation rate? Data from 2007 shows that in a sample of 38 colleges and universities in the U.S., the average expenditure per full-time student was $8,093.43 with a standard deviation of $472.39. The average graduate rate was 46.73% with a standard deviation of 11.15. The correlation between the variables was 0.585. All answers should be rounded to 4 places behind the decimal.

    1. a)  Find the regression line of the graduation rate on student expenditure. Be sure to state the explanatory and response variable.
