Of them, only 348 knew that the legislative branch of the American government is the branch that has the authority to declare war (please write all numbers to at least four decimal places). a. Calculate the value of the point estimate of the parameter. b. What is the name of the statistic that we can use to measure the uncertainty of this point estimate? Otest statistic O null hypothesis standard deviation O standard error c. Compute that value that measures the uncertainty. d. Calculate a 95% confidence interval for the population proportion of college-age American adults in this group. < p < e. Before learning the statistic, a pundit guessed that the value was actually 38%. Should this pundit be surprised by the survey result? O No, the Z-score is not unusual. Yes, the Z-score is unusual.
