Blood pressure: 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 0.2. A sample of 37 U.S. adults is chosen. Use the TI-84 Plus Calculator as needed. Round the answer to at least four decimal places. Part 1 of 5 Is it appropriate to use the normal approximation to find the probability that more than 48% of the people in the sample have high blood pressure? It is not v appropriate to use the normal curve, since np = 7.4 10 and n (1 - p) = 29.6 ||2 10. Part 2 of 5 A new sample of 82 adults is drawn. Find the probability that more than 32% of the people in this sample have high blood pressure. The probability that more than 32% of the people in this sample have high blood pressure is 0.0033
