Null Hypothesis (H0): There are no significant differences in the means of the groups (OnePlus, Apple, Samsung, Xiaomi). Alternative Hypothesis (H1): At least one group mean is significantly different from the others. F-value: 8.63 P-value: 3.97, F critical value: 2.6994 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: 3.97 > 0.05 (significant),F-value: 3.58 > 2.6994 (also significant)
Conclusion: Since the P-value is more 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 OnePlus, Apple, Samsung, Xiaomi.
