b. A random sample of 300 Status cheque accounts at Capital Bank showed that 48 were overdrawn. When 250 Elite cheque accounts at the same bank were randomly checked, it was found that 55 were overdrawn. Can the bank manager conclude that more Elite cheque account clients, proportionately, are likely to be overdrawn than Status cheque account clients? Test this hypothesis at the 4% level of significance. What conclusion can be drawn? (10)
