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 is 0.3. A sample of 31 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 47% of the people in the sample have high blood pressure? It is not appropriate to use the normal curve, since np = 9.3 10 and n (1 - p) = 21.7 10. Part 2 of 5 X A new sample of 83 adults is drawn. Find the probability that more than 41% of the people in this sample have high blood pressure. The probability that more than 41% of the people in this sample have high blood pressure is | 0.4262 Correct Answer: 0.0144Part 3 of 5 X Find the probability that the proportion of individuals in the sample of 83 who have high blood pressure is between 0.20 and 0.32. The probability that the proportion of individuals in the sample of 83 who have high blood pressure is between 0.20 and 0.32 is -1.988 Correct Answer: 0.6311 Part 4 of 5 Find the probability that less than 21% of the people in the sample of 83 have high blood pressure. The probability that less than 21% of the people in the sample of 83 have high blood pressure is | 0.0368 Part: 4 / 5 Part 5 of 5 Would it be unusual if more than 41% of the individuals in the sample of 83 had high blood pressure? It (Choose one) v be unusual if more than 41% of the individuals in the sample of 83 had high blood pressure, since the X 5 probability is
