The SPSS output is:
The hypothesis being tested is:
H0: µ1 = µ2 = µ3
Ha: Not all means are equal
The p-value is 0.553.
Since the p-value (0.553) is greater than the significance level (0.05), we cannot reject the null hypothesis.
Therefore, we cannot conclude that there is a difference between the grade of different ethnic groups.
