Question

Given two independent samples, conduct a hypothesis test for the difference between the means. Consider a significance level of 0.05. Use a confidence interval to decide whether to reject or not $H_0$. $H_0: \mu_1 - \mu_2 = 0$ $H_1: \mu_1 - \mu_2 \neq 0$ Sample (1) Sample (2) 25 21 25 21 28 22 23 24 28 25

Step 1

Sample 1: Mean (x̄1) = (25 + 25 + 28 + 23 + 28) / 5 = 25.8 Standard deviation (s1) = √[((25-25.8)² + (25-25.8)² + (28-25.8)² + (23-25.8)² + (28-25.8)²) / 4] = 2.68 Sample 2: Mean (x̄2) = (21 + 21 + 22 + 24 + 25) / 5 = 22.6 Standard deviation (s2) = √[((21-22.6)² Show more…
