Question:
14.59 Catching a Cold Is your chance of getting a cold influenced by the number of social contacts you have? A recent study showed that the more social relationships you have, the less susceptible you are to colds.22 A group of 276 healthy men and women were grouped according to their number of relationships (such as parent, friend, church member, neighbour). They were then exposed to a virus that causes colds. An adaptation of the results is shown in the table:
a. Do the data provide sufficient evidence to indicate that susceptibility to colds is affected by the number of relationships you have? Test at the 5% signifi- cance level.
b. Based on the results of part
a, describe the nature of the relationship between the two categorical variables: cold incidence and number of social relationships. Do your observations agree with the conclusions of the study?
