Null Hypothesis (H₀): There are no significant differences in the means of the groups (Limonata, Slice, Pepsi and Campa Cola)
Alternative Hypothesis (H₁): At least one group mean is significantly different from the others.
F-value: 13.9127, P-value: 1.3E-07, F critical value: 2.69939
If the P-value is more than the significance level (commonly 0.05), we reject the null hypothesis.
Alternatively, if the F-value is greater than the F critical value, we also reject the null hypothesis.
P-value: 0.0000780 < 0.05 (significant),F-value: 8.04 > 2.699 (also significant)
Conclusion:
Since both the P-value is less than 0.05 and the F-value exceeds the F critical value, we reject the null hypothesis. This indicates that there is a statistically significant difference in the means of at least one of the Limonata, Slice, Pepsi, Campa Cola.
