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 is0.3. A sample of31U.S. adults is chosen. Round the answer to at least four decimal places.

Is it appropriate to use the normal approximation to find the probability that more than47%of the people in the sample have high blood pressure? Itis notappropriate to use the normal curve, since=

np=9.3<10 and=n1p 21.710.

A new sample of83adults is drawn. Find the probability that more than41%of the people in this sample have high blood pressure.The probability that more than41%of the people in this sample have high blood pressure is0.0144.

Find the probability that the proportion of individuals in the sample of83

who have high blood pressure is between0.20and0.32. The probability that the proportion of individuals in the sample of83who have high blood pressure is between0.20and0.32is_0.6311

Would it be unusual if more than41% of the individuals in the sample of 83had high blood pressure? Itwouldbe unusual if more than41

%of the individuals in the sample of83had high blood pressure since the probability is____
