High blood pressure has been identified as a risk factor for heart attacks and strokes. The proportion of U.S. adults with high blood pressure is 0.46. A sample of 84 U.S. adults is chosen. a) What is the sampling distribution of the sample proportion of U.S. adults who have high blood pressure? (i.e. What is the sampling distribution of the sample proportion, p?) Using Table B find the following: b) Find the probability that the proportion of individuals in the sample who have high blood pressure is between 0.42 and 0.58. ) Find the probability that less than 38% of the people in the sample have high blood pressure. d) Find the probability that more than 57% of the people in the sample have high blood pressure. e) Would it be unusual if less than 40% of the individuals in the sample of 84 had high blood pressure?
