Question: look at the table for the paired samples test to...

Question details
  1. Look at the table for the Paired samples test to find your t calculated, df, and significance. Remember that significance level will appear in the Sig (2-tailed) column. Any value that is smaller than .05 will be significant at the .05 level or higher. In a sentence describe the results and report them in APA style, including r2 and evaluation (you will need to calculate r2 by hand).

3. What type of error in hypothesis testing is possible given the above result? How likely is this error given r2?

4. Briefly describe why a paired samples t-test was calculated for the school IQ data, but an independent samples t-test was calculated for the depression and sleep data.
