High blood pressure has been identified as a risk factor for heart attacks and strokes. The proportion of us adults with high blood pressure is 0.4. A sample of 37 us adultsis chosen. Is it appropriate to use the normal approximation to find the probability that more than 45% of the people in the sample have high blood pressure? It ---- appropriate to use the normal curve, since np =

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 0.40. A sample of 41 U.S. adults is chosen. Use Cumulative Normal Distribution Table as needed. Round your answers to at least four decimal places if necessary. (a)Is it appropriate to use the normal approximation to find the probability that more than 44% of the people in the sample have high blood pressure? It (Choose one) appropriate to use the normal curve, since np = (Choose one) 10 and n(1 - p) = (Choose one) 10.

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 41 U.S. adults is chosen. Use the TI-84 Plus Calculator as needed. Round the answer to at least four decimal places. Is it appropriate to use the normal approximation to find the probability that more than 44% of the people in the sample have high blood pressure? It (is or is not) appropriate to use normal curve since np= ________ and n(1-p)=________.
