Conclusion – As the P-value of the hypothesis is 0.63 is more than 0.05 we accept the null hypothesis meaning all are same. Based on the ANOVA results, there is sufficient evidence to conclude that there are significant differences in customer preference scores among the four biscuits. There is no statistically significant difference between the average values of Oreo, Bourbon, Jim-Jam and Marie Gold .The p-value (0.63) is much higher than the typical threshold of 0.05, meaning the differences in their averages could very likely be due to random chance.
