Test the null hypothesis that the three population mean scores are equal. Use ? = 0.05

What will be an ideal response?

H0 : ?1 = ?2 = ?3
H1 : ?i ? ?j for at least one pair (?i, ?j)
Since p-value = 0.7862, we fail to reject H0 at ? = 0.05, and conclude that there is insufficient evidence that the three population mean scores are not equal.
