How do you conduct and interpret hypothesis tests for two population means to determine a significant difference in statistics?

Answer 1

To conduct hypothesis tests for two population means, first state the null hypothesis (H0) that the means are equal and the alternative hypothesis (H1) that they are not. Choose a significance level (α), collect sample data, and calculate the test statistic (e.g., t-test or z-test). Compare the test statistic to critical values or use the p-value approach. If the test statistic exceeds the critical value or the p-value is less than α, reject H0. Interpret results in context, considering effect size and practical significance.
