M2160-1      4th Homework Assignment.      Due Mar. 3, 2006.

1. Many references to research about mathematics education are available in the Department of Mathematics Math Education page http://www.math.utah.edu/~aroberts/MathEd1.html. There you can find interesting statistics about national and international trends in mathematics education. It will lead you to the data here, gathered from the National Center for Education Statistics website http://nces.ed.gov/nationsreportcard/mathematics/results2003/stateresults.asp.

   The data file "SchoolData.txt" has recent Department of Education statistics on enrollments in public elementary and secondary school, populations as well as teacher salaries, expenditure per pupil and pupil/teacher ratios by state. Write a program to read the data and compute the values for each column for the nation. (This data was gathered from the National Center for Education Statistics tables. You can look up the national numbers to compare to your numbers.) Be sure to explain the formulas you used to recover the national numbers.

   You can copy the data file to your computer and name it "SchoolData.txt."

   SchoolData.txt

2. Write a program to enter three numbers and compute their greatest common divisor. If you use a function subprogram that computes the GCD two numbers, be sure to explain why it can be used to compute the GCD of three numbers.
