You should review quiz#1, #2 and #3 but in particular you should review the following. Remember, there will be no SAS questions.

• Normal Theory:

  Try these problems. Check this link for solutions. If you have FPP sections 5.2 and 5.5 may also help. In addition you can review the following.

  
  
  • Transformation problems:
    These problems are taken from FPP pp94; #4. Follow this link for the questions and solutions. For additional practice with look-up problems work FPP pp84 #1. Follow this link for the questions and solutions.
  • Percentile problems:
    Work problems at this link. You may also try FPP pp92; #1-3.
  
  
• Regression & Normal Theory:

  Try this problem. Check this link for the solution. Also try the problem (with solution) worked in class. You may also want to try FPP pp187 #1 and pp197 #1 for additional practice. Here is a regression problem and the solution. FPP 7 should be reviewed if you have trouble with graphs and the notion of slope and intercept. FPP 11.1, 11.2, 11.4, 11.5 and FPP 12; pp202-207 may also help.

  If you need additional practice estimating the slope and intercept of the regression line given the correlation coefficient and the standard deviation of y and x try these FPP problems:

  • FPP pp213; #1 and pp214; #2
  • Extra practice

You should know how to interpret a correlation coefficient, how to interpret the slope of a regression line and how to interpret the intercept.
