According to a survey, a majority of households have tried to cut long distance phone bills. Of those who have tried to cut bills, 32% have done so by switching long distance companies. Suppose busniess researchers belive that this figure may be higher today. To test this theory, a researcher conducts another survey by random cantacting 80 households who have tried to cut long distance phone bills. If 39% of the contacted households say they have tried to cut their long distance phone bills by stwitching long distance companies, is this result enough evidence to state that a significantly higher proportion of households are trying to cut long distance phone bills by switching companies?
