Some scientists believe that the sickle-cell trait lowers the risk of developing malaria. To explore this belief, 398 children in Africa were tested for the sickle-cell trait and malaria. The results are presented in Table 1 (attached). Test, at the 5% level of significance, whether there is an association between the sickle- cell trait and malaria. Make sure you show all your workings in the 6 steps.
