Opinion Research has said that 49.46% of U.S. adults have purchased life insurance. Suppose that for a random sample of 47 adults from a given U.S. city, a researcher finds that only 48.18% of them have purchased life insurance. At the 0.01 level, is this sample finding significantly lower than the 49.46% reported by Opinion Research? Select one: a) z_stat = -2.11 and z_cr = -2.33 : The sample finding significantly lower than the reported percentage by Opinion Research b) z_stat = -2.11 and z_cr = -2.33 : The sample finding is not significantly lower than the reported percentage by Opinion Research c) z_stat = -2.8696 and z_cr = -2.58 : The sample finding is not significantly lower than the reported percentage by Opinion Research d) z_stat = -2.8696 and z_cr = -2.58 : The sample finding significantly lower than the reported percentage by Opinion Research
