Null Hypothesis (H0): There are no significant differences in the means of the groups (Tata Moters, Honda, Suzuki ,Kia). Alternative Hypothesis (H1): At least one group mean is significantly different from the others. F-value: 11.95112 P-value: 0.00000112, F critical value: 2.703594 If the P-value is less 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: 0.00000112
< 0.05 (significant),F-value: 11.95112 > 2.703594 (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 Tata Moters, Honda, Suzuki ,Kia
