Here’s how ChatGPT can help you with hypothesis testing:
1. State the null and alternative hypotheses
Null Hypothesis (H0): The average sales of product A are equal to or less than the average sales of product B.
Alternative Hypothesis (HA): The average sales of product A are higher than the average sales of product B.
2. Choose a significance level
Select a significance level (?) to determine the threshold for rejecting the null hypothesis. Common choices are 0.05 (5%) or 0.01 (1%).
3. Perform a t-test
Calculate the t-statistic and p-value to evaluate the hypothesis. The t-test compares the means of two groups to determine if they are significantly different. In this case, you would perform an independent two-sample t-test.
4. Interpret the results
Based on the p-value obtained from the t-test, you can either reject or fail to reject the null hypothesis.
If the p-value is less than the chosen significance level (?), you reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis. If the p-value is greater than ?, you fail to reject the null hypothesis.
