Good Morning, I have questions that need Answers Please.

1.) Part 3?

Coffee: The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 300 U.S. adults is selected. Round your answers to at least four decimal places as needed. (a) Find the mean pa. P The mean [1.3 is -. l Your answer is conect. (b} nd the standard deviation 0A. P The standard deviation on is 0.0280 . P - Your answer is conect. However, 1you don't need to put zeros at the end of the number. Alternate Answer: The standard deviation GA is 0.028. Part 3 of 6 (c) Find the probability that more than 63% of the sampled adults drink coffee daily. The probability that more than 63% of the sampled adults drink coffee daily isAbout 5% of employed adults in the United States held multiple jobs. A random sample of 60 employed adults is chosen. Use the 1184 Plus calculator as needed. (a) Is it appropriate to use the normal approximation to nd the probability that less than 3% of the individuals in the sample hold multiple jobs? If so, nd the probability. If not, explain why not. It E appropriate to use the normal curve, since up = 10. l Your answer is lCDTTBCt. Correct Answer: It is not appropriate to use the normal curve, since up = 3 Y 10. - Your answer is conect. Find the probability that less than 29% of the 'eshmen in the sample are planning to major in a STEM discipline. The probability that less than 29% of the freshmen in the sample are planning to major in a STEM discipline is D. Blood pressure: High blood pressure has been identied as a risk factor for heart attacks and sb'okes. The proportion of U.5. adults with high blood pressure is 0.3. A sample of 33 U.S. adults is chosen. Use the "Fl84 Plus Calculator as needed. Round the answer to at least four decimal places. Is it appropriate to use the normal approximation to nd the probability that more than 43% of the people in the sample have high blood pressure? It appropriate to use the normal curve, since up = _10 mum l Your answer is comect. A new sample of 30 adults is drawn. Find the probability that more man 38% of me people in this sample have high blood pressure. The probability that more than 38% of the people in this sample have high blood pressure is -. l Your answer is COITEEI. Find the probability that the proportion of individuals in the sample of 80 who have high blood pressure is between 0.24 and 0.35. The probability that the proportion of individuals in the sample of 80 who have high blood pressure is between 0.24 and 0.35 is D . Below, :1 is the sample size,p is the population proportion of successes, andXis the number of successes in the sample. Use the normal approximation and the 1184 Plus calculator to nd the probability. Round the answer to at least four decimal places. n=85,p=0.43 P {31> 32) D Big babi: A government agency reports that 2.0% of baby boys 68 months old in the United States weigh more than 25 pounds. A sample of 15] babies is studied. Use the 9 Cumulative Normal Distribution Table if needed. Round the answer to at least four decimal places. (a) Approximate the probability that more than 42 babies weigh more than 25 pounds. (b) Approximate the probability that 36 or more weigh more than 25 pounds. (c) Approximate the probability that the number who weigh more than 25 pounds is between 30 and 40 exclusive. The probability that more than 42. babies weigh more than 25 pounds is D. The probability that 36 or more babies weigh more than 25 pounds is D . The probability that the number who weigh more than 25 pounds is between 30 and 40 exclusive is D . Is it reasonable to treat the following as a sample from an approximately normal population? Explain. Part 1 of 4 (a) The following dotplot illustrates a sample. 6 8 9 10 The dotplot reveals a large degree of skewness . Therefore, we cannot treat this as a sample from an approximately normal population. . Your answer is correct. Part: 1 / 4 Part 2 of 4 (b) The following boxplot illustrates a sample. 6 (D - CO - 10 The boxplot reveals a large degree of skewness V. Therefore, we cannot treat this as a sample from an approximately normal population. X 5 Your answer is incorrect.A manufacturer of aluminium cans measured the level of impurities in 24 cans. The amounts of impurities, in percent, were as follows. 2.0 0.8 5.8 1.2 1.7 1.4 7.2 1.5 9.4 1.9 0.9 2.8 3.2 3.4 0.? 3.? 3-8 4.3 4.8 1.4 6.7 4.7 8.3 1.4 Construct a boxplot for me given sample
