Please help.
I ran an ANOVA for this test. When I printed out the Word Doc in Google Docs, it eliminated a few of the values I highlighted in the ANOVA table. Use your knowledge of the ANOVA table and fill in the blanks. In this test, there are 5 groups and each group consist of 20 samples (100 total). df MS F ANOVA Source of Variation Between Groups Within Groups Total SS 190 Fcrit 2.77 690 Suppose that the researcher is not happy about those new confidence intervals. (As we all know, 95% is the standard because it is the best!) So, you code the data and run a regression model. Your output is below.
