1.After performing an ANOVA test, with (3,4) degrees of freedom,
for data collected during an experiment trying to determine if
there is at least one difference between groups. You get a
calculated F value of 7.52. Using the table below, find the
appropriate critical F value. What should be your conclusion(s),
based on those 2 F values and α? Check all that apply.
