Title: Soft Drink Preferences Ratings
Introduction: Soft drinks are non-alcoholic, carbonated beverages typically sweetened with sugar or artificial sweeteners. They come in various flavors, including cola, fruit, and citrus. Many soft drinks also contain caffeine and other additives to enhance flavor or provide energy. They are widely consumed around the world as refreshing drinks, often served chilled. However, excessive consumption has been linked to health concerns like obesity and tooth decay due to high sugar content.

Objective: To compare the four different types of soft drink preferences.
Data collection:
Individual participants provided ratings for Pepsi, Mountain dew, Coca Cola, and Mirinda 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 beverages.
Data analysis:
The ratings were then compiled to analyze consumer preferences using ANOVA: single factor, allowing for statistical evaluation of differences in beverage preferences.
The hypothesis for the test is:
- Null Hypothesis (H0): It states that all beverage preferences are the same.
- Alternative Hypothesis (H1): It indicate that at least one beverage 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 – Pepsi, Mountain dew, Coca Cola, and Mirinda has a significantly different preference level among respondents.
