5.5.2 - Paired Means Example: Age

Research question: On average, are husbands older than their wives?

Step 1: The data are paired by couple. This is a paired means test.

\(H_0: \mu_d=0\)

\(H_a: \mu_d > 0\)

Step 2: We constructed a randomization distribution in StatKey using the built in dataset.

Step 3: \(p < 0.001\)

Step 4: Reject the null hypothesis

Step 5: There is evidence that in the population, on average, husbands are older than their wives.
