# Question

In March 1995, The Harris Poll reported that 80% of parents spank their children. Suppose a recent poll of 1030 adult Americans with children ﬁnds that 781 indicated that they spank their children. If we assume parents’ attitude toward spanking has not changed since 1995, how many of 1030 parents surveyed would we expect to spank? Do the results of the survey suggest that parents’ attitude toward spanking may have changed since 1995? Why?
