Data from the office for national Statistics show that the mean age at which men in great Britain get married is 30.8 years (the Guardian, February 15, 2013). A news reporter noted that this represents a continuation of the trend of waiting until a later age to wed. A new sample of 47 recently wed British men provided their age at the time of marriage. These data are contained in the data file Britain Marriages. Do these data indicate that the mean age of British men at the time of marriage exceeds the mean age in 2013? Test this hypothesis at a = .05. What is your conclusion?
