Title: TEA Companies Preferences Ratings
Introduction:
In India, tea is most commonly consumed as chai, a spiced tea blend made by brewing black tea with milk, sugar, and spices such as cardamom, ginger, cloves, and cinnamon. Chai is sold on almost every street corner by tea vendors known as chaiwalas and is a social beverage, enjoyed by people across different regions and social strata.

Objective:
To compare the four different types of Tea companies preferences.
Data collection:
Individual participants provided ratings for Taj Mahal, Dabur, Tata tea and Wagh Bakri on a scale of 1 to 10. Each rating was collected independently to reflect personal preferences, ensuring an unbiased analysis of consumer tastes and trends across the tea.
Data analysis:
The ratings were then compiled to analyze consumer preferences using ANOVA: single factor, allowing for statistical evaluation of differences in tea preferences.
The hypothesis for the test are:
- Null Hypothesis (H0): It states that all tea preferences are the same.
- Alternative Hypothesis (H1): It indicate that at least one tea company is rated significantly differently.

Since the P-value is 0.045 is less than the significance level of 0.05, we accept the Alternative Hypothesis.
Conclusion:
The ANOVA: single factor analysis yielded a P-value less than 0.05, leading to rejecting the Null Hypothesis. This confirms that at least one beverage— Taj Mahal, Dabur, Tata tea and Wagh Bakri —has a significantly different preference level among respondents.
