Good Afternoon, I need answers to these questions, please.

1.) Part 1?

About 15% of employed adults in the United States held multiple jobs. A random sample of 61 employed adults is thosen. Use the 1184 Plus calculator as needed. (a) Is it appropriate to use the normal approximation to nd the probability that less than 8.5% of the individuals in the sample hold multiple jobs? If so, nd the probability. If not, explain why not. It (Choose one) 1' appropriate to use the normal curve, since up = D - (Choose one) T 10. Future scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A research group reported that 26% of freshmen entering college in a recent year planned to major in a STEM discipline. A random sample of 75 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 29% of the freshmen in the sample are planning to major in a STEM discipline? It (Choose one) V appropriate to use the normal curve, since np X 5 (Choose one) A 10 and n (1 - p) = (Choose one) 10. 2Big babim: A government agency reports that 19% of baby boys 63 months old in the United States weigh less than 25 pounds. A sample of 14'? babies is studied. Use the Cumulative Normal Distribution Table if needed. Round the answer to at least four decimal places. (a) Approximate the probability that less than 39 babies weigh less than 25 pounds. (b) Approximate the probability that 35 or fewer weigh less than 25 pounds. ((2) Approximate the probability that the number who weigh less than 25 pounds is between 32 and 42 exclusive. The probability that less than 39 babies weigh less than 25 pounds is D . The probability that 35 or fewer babies weigh less than 25 pounds is [j . The probability that the number who weigh less than 25 pounds is between 32 and 42 exclusive is D . Is it reasonable to treat the following as a sample from an approximately normal population? Explain. Part: 0 / 4 Part 1 of 4 (a) The following dotplot illustrates a sample. 9 10 The dotplot reveals (Choose one) Therefore, we (Choose one) treat this as a sample from an approximately normal population. X can 5 cannotIs it reasonable to treat the following as a sample from an approximately normal population? Explain. Part: 0 / 4 Part 1 of 4 (a) The following dotplot illustrates a sample. 8 9 10 The dotplot reveals (Choose one) Therefore, we (Choose one) V treat this as a sample fro an outlier ation.
