Suppose that a poll taken 10 years ago found that 55% of parents spank their children. Suppose a recent poll of 150 adults with children finds that 65 indicated that they spank their children. Complete parts (a) and (b) below (a) Assuming parents' attitude toward spanking has not changed since the original poll, how many of the 150 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) (b) Do the results of the survey suggest that parents' attitude toward spanking may have changed since the original pol? Why? OA No. 65 is within one standard deviation of the expected amount of adults that spank their children. OB. Yes, 65 is outside the "usualr observation interval of this survey. OC. Yes, 65 is less than the expected amount of adults that spank their children. O D. No, 65 is inside the "usual observation interval of this survey.
