Suppose that a poll taken 10 years ago found that 55% of parents spank their children. Suppose a recent poll of 450 adults with children finds that 216 indicated that they spank their children. Assuming parents' attitude toward spanking has not changed since the original poll, how many of the 450 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.)
