Below is an ANOVA summary table. Based on these data, would you follow this ANOVA up with post hoc tests?
| Source | SS | df | MS | F |
| Between-Groups | 60.72 | 3 | 20.24 | 3.88 |
| Within-Groups | 213.61 | 41 | 5.21 | |
| Total | 274.33 | 44 |
for 0.05 level and (3,41) degree of freedom , critical value of F =2.83
since test statistic 3.88 > critical value 2.83 , we reject null hypothesis at 55 level and conclude that some population means differs
therefore post hoc tests is required to know which means differs,

QUESTION 1 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 4 groups (J = 4), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places. QUESTION 2 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 6 groups (J = 6), what would...

Four groups of college students underwent a sleep deprivation
study. There were 6 participants per condition. They had been
deprived of sleep for 0, 6, 12, or 24 hours. Afterwards, a memory
test was given. An ANOVA was conducted in Microsoft Excel and the
results are given in the table below. Follow-up this ANOVA with a
post hoc test (α= .01) to determine which groups differed.
Construct a table of mean differences to organize the means. Make
certain to explain...
