Suppose that a poll, taken 10 years ago found that 69% of parents spank their children. Suppose a recent poll of 200 adults with children finds that 119 indicated that they spank their children. Assuming parents' attitude toward spanking has not changed since the original poll, how many of the 200 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 O A. Yes, 119 is more than two standard deviations from the expected number of adults who spank OB. No, 119 is within one standard deviation of the expected number of adults who spank O c. Yes, 119 is less than the expected amount of adults that spank their children. O D.…

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He has good reason to believe that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 124 mm Hg and the standard deviation of the sample to be 20 mm Hg. Based on this information, complete the parts below. A. H0: H1: B. Suppose that the researcher decides to reject the null hypothesis. Would the research be making a type I or type II error?
