1. Data on students in liberal arts colleges in the U.S. wascollected, and the average cost per student was recorded for eachschool. The following five-number summary was calculated for thisdata set: minimum= $17,554; first quartile = $23,115; median =$26,668; third quartile = $45,879; maximum=$102,262.

Suppose an algebra professor found that the correlation (r)between study time (in hours) and exam score (out of 100) is +.80,and the regression line was found to be ExamScore = 20 +4*HoursStudied. He arrived at this equation through years ofcollecting data on his students.

The quantitative reasoning GRE scores are known to approximatelyhave a Normal distribution with a mean of μ = 151 points and astandard deviation of σ = 8 points.  

FORMAT FOR PARTS 1-3: lowerbound, upperbound. using numbers asexample:  5,10

1.  Use the Empirical Rule to specify the ranges intowhich 68% of test takers fall.

2. Use the Empirical Rule to specify the ranges into which 95%of test takers fall.

3. Use the Empirical Rule to specify the ranges into which 99.7%of test takers fall .

FOR ANSWERS 4-5 type number ONLY: for exampleif 10% just type 10

4.  What percentage of test takers score lower than159?

5. What percentage of test takers scored between 135 and151?
