Question
You intend to conduct an ANOVA with 4 groups. The number of subjects in each group is listed below.
Group | Number of subjects |
1 | 19 |
2 | 8 |
3 | 18 |
4 | 6 |
b) What are the degrees of freedom for the denominator (df within)?
c) If you ran an ANOVA hypothesis test at the 0.05 alpha level with the number of subjects listed in the table above, what would be the crtical F-value? Note: To get the critical F-value, type =finv(0.05,your df between, your df within) in any white cell.
d) If you did get a significant result running the ANOVA test, how many pair-wise comparisons would you need to check on the Post-Hoc section of the ANOVA sheet?

- All other conditions being equal, does a larger sample size increase or decrease the corresponding magnitude of the z or t value of the sample test statistic?arrow_forwardAcne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.arrow_forwardIs the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused by humans in the west? 360 of the 501 randomly selected wildfires looked at in the south were caused by humans while 435 of the 588 randomly selected wildfires looked at the west were caused by humans.
