Suppose that a poll taken 10 years ago found that 55% of parents spank their children. Suppose a recent poll of 350 adults with children finds that 165 indicated that they spank their children. (a) Assuming parents' attitude toward spanking has not changed since the original poll, how many of the 350 parents surveyed would be expected to spank their children? The expected amount of parents surveyed that would spank their children is (Round to the nearest whole number as needed.)
