Below, * is the sample size, y is the population proportion and y is the sample proportion. Use the Central Limit Theorem and the TI-84 calculator to find the probability. Round the answer to at least four decimal places. 1 = 100 p = 0.18 P(0.14 0.60 ) = XCoffee: The National Coffee Association reported that 63 % of U.S. adults drink coffee daily. A random sample of 250 U.S. adults is selected. Round your answers to at least four decimal places as needed. Part: 0 / 6 Part 1 of 6 (a) Find the mean um. The mean LA is XSmartphones: A poll agency reports that $6 of teenagers aged 12 - 17 own smartphones. A random sample of 270 teenagers is drawn. Round your answers to at least four decimal places as needed. Part: 0 / 6 Part 1 of 6 (a) Find the mean us. X The mean un isFuture scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A research group reported that 27 to of freshmen entering college in a recent year planned to major in a STEM discipline. A random sample of $5 freshmen is selected. Round the answer to at least four decimal places. Part: 0 / 6 Part 1 of 6 Is it appropriate to use the normal approximation to find the probability that less than 30 of the freshmen in the sample are planning to major in a STEM discipline? It (Choose one) |appropriate to use the normal curve, since Ap = (Choose one) * 10 X 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 39 U.S. adults is chosen. Use the TI-84 Plus Calculator as needed. Round the answer to at least four decimal places. Part: 0 / 6 Part 1 of 6 Is it appropriate to use the normal approximation to find the probability that more than 43 0% of the people in the sample have high blood pressure? It (Choose one) v appropriate to use the normal curve, since mp = (Choose one) > 10 X 5 and m (1 - p) = (Choose one) 10
