Suppose that an experiment is carried out to see if there is any relation between a man€™s age and whether he wears a moustache. Suppose that 100 men, 18 years of age or older, are selected at random, and each man is classified according to whether or not he is between 18 and 30 years of age and also according to whether or not he wears a moustache. The observed numbers are given in Table 10.17. Test the hypothesis that there is no relationship between a man€™s age and whether he wears a moustache.
