The Indian River County Health Department needs to estimate the proportion of county residents with high blood pressure. A health department researcher found that 672 out of a random sample of 1507 county residents had high blood pressure . Determine the point estimate, and the sample standard deviation, hat p; s hat p . Round the sample proportion to four decimal places and round the standard deviation to six decimal places, if necessary. hat p = Box; s_{p} = Using a 99% confidence level, determine the margin of error, E, and a confidence interval for the true proportion of all Indian River County residents who have high blood pressure. Report the confidence interval using interval notation. Round solutions to four decimal places, if necessary. The margin of error is given by E = A 99% confidence interval is given by
