Hypothesis:
Null Hypothesis (H0): All are the same.
Alternative Hypothesis (H1): Anyone of them is different.
Since the P-value is more than the significance level (0.05), we accept the null hypothesis. This means that there is sufficient evidence to conclude that all the online food delivery platforms have the same average rating.
