Question
**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 0.4. A sample of 39 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 43% of the people in the sample have high blood pressure? It **is** appropriate to use the normal curve, since \( np = 15.6 \geq 10 \) and \( n(1-p) = 23.4 \geq 10 \). **Part 2 of 6** Find the probability that more than 43% of the people in this sample have high blood pressure. The probability that more than 43% of the people in this sample have high blood pressure is **0.3511**.

The probability that more than 38% of the people in this sample have high blood pressure is **0.0030**. The image includes a text box that contains the probability value "0.0030," which is marked with an "X" indicating that it is incorrect. There are also two buttons beside the text box: one with an "X" symbol (likely for cancelling or clearing the entry) and one with a circular arrow (likely for resetting or retrying the entry). There are no graphs or diagrams present.
