Question

A company that sells sunscreen products wants to know whether there is a relationship between people's hair colour and their tendency to apply sunscreen before going outside. For example, it may be that redheads and blondes are more sensitive to the sun, and are therefore more likely to use sunscreen. A random sample of adults was selected, and their hair colour and tendency to use sunscreen was recorded, with the results shown in Exhibit 12.33.
At the 5% level of significance, is there evidence of a relationship between hair colour and tendency to use sunscreen?
