Tasks 2: ANOVA (days as factor with 2 levels)
This problem continues with the same data set presented above. Continue with a significance level .
Run the ANOVA using day as the factor (2 levels: Monday & Friday):
(report answer accurate to 3 decimal places)
(report answer accurate to 4 decimal places)
Decision regarding the statistical test:
Final conclusion:
Questions for reflection: First, though this is not exactly how multiple confidence interval should be interpreted, did the results of this ANOVA agree with the confidence intervals obtained from Task 1? Second, what other statistical test might have been used to obtain the same result as this ANOVA?
Finally, though not specifically addressed here, run the necessary tests to confirm that the assumptions for an ANOVA have not been violated with these samples.
