Question: In a class of remedial English that was taught by the lecture method, 52 out of 75 students completed the course with a passing grade. In the same course with

computer-assisted instruction, 69 out of 95 completed the course with a passing

grade. At the .05 level, is there a significant difference in the passing rates for the

two different methods of instruction? Use the following data to:

x y
2 15
1 18
3 11
4 7
2 10
1 16
5 4
6 2
  1. draw a scatter plot
  2. find the coefficient of correlation and test the significance at the .05 level
  3. find the regression line
  4. predict y′ for x = 5
  5. find the coefficients of determination and non-determination
  6. find the standard error of estimate
  7. find the 95% confidence interval for the number of alcoholic drinks of

x = 5
