A researcher wants to test to see if husbands are significantly older than their wives. To do this, he collects the ages of husbands and pairs them with the ages of their respective wives for a random set of married couples. Find the test statistic and degrees of freedom for an appropriate hypothesis test using the data set below. Let the difference d for each couple be computed as d=husband−wife. Assume that the ages are normally distributed. Round the test statistic to three decimal places.
