![Researchers at a hospital developed a new low-calorie diet to investigate its effectiveness in reducing weight. They asked 27 middle-aged individuals to follow the diet for three months. Participants' weights (in kilograms) were recorded at the beginning of the study and after the three-month diet period. The data are available in the file "diet.xlsx."
The goal is to determine if the low-calorie diet effectively reduces weight in middle-aged people using a 0.05 significance level (alpha = 0.05).
Here are the hypotheses and statistical details to be filled in:
- The null hypothesis \( H_0 \) is: \( \mu_{\text{beginning}} - \mu_{\text{after}} = 0 \).
- The alternative hypothesis \( H_a \) is: \( \mu_{\text{beginning}} - \mu_{\text{after}} \neq 0 \).
Choices and numerical values needed:
- The t statistic is: [Select Value]
- The p-value is: [Select Value]
- The test indicates: [Conclusion based on statistical test]
