Suppose that a poll taken 10 years ago found that 56% of parents spank their children. Suppose a recent poll of 500 adults with children finds that 247 indicated that they spank their children. Assuming parents' attitude toward spanking has not changed since the original poll, how many of the 500 parents surveyed would be expected to spank their children? Do the results of the survey suggest that parents' attitude toward spanking may have changed since the original poll? Why? We would expect parents to spank their children. (Round to the nearest whole number as needed.) Do the results of the survey suggest that parents' attitude toward spanking may have changed since the original poll? Choose the correct answer below. A. No, 247 is within two standard deviations of the expected number of adults who spank. B. No, 247 is within one standard deviation of the expected number of adults who spank. C. Yes, 247 is less than the expected amount of adults that spank their children. D. Yes, 247 is more than two standard deviations from the expected number of adults who spank.
