The proportion of U.S. adults with high blood pr 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 |2 10 and n (1 – p) = 23.4 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 .3511 AIarrow_forward
- Uttar Pradash, Rajasthan and Bihar are subregions of India. It is reported that 94% of Uttar Pradash residents say Hindi is their first language of choice, 89% of Rajasthan residents say Hindi is their first language of choice, and 78% of Bihar residents say Hindi is their first language of choice. Suppose that 8 residents are randomly sampled from each of these regions (so 3x8 total residents are sampled). Calculate the probability that they all say Hindi is their first language of choice. Use decimal notation and three decimal place accuracy.arrow_forwardSuppose that we know that 33.8% of the people born in the United Sates between 1936 and 1951 have BLUE eyes.
