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 42 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 6 Is it appropriate to use the normal approximation to find the probability that more than 51% of the people in the sample have high blood pressure? It is v appropriate to use the normal curve, since np = | 12.6 | 2 v 10 and n (1 - p) = |29.4| 2 v 10.
