A genetic experiment with peas resulted in one sample of offspring that consisted of 416 green peas and 160 yellow peas. a. Construct a 95% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? rOontogos in decimal form

A) What proportion of commercial airline pilots are more than 40 years of age? Suppose an analyst has access to a list of all pilots who are members of the Air Line Pilots Association. If this list is used as a frame for the study, she can randomly select a sample of pilots, contact them, and ascertain their ages. From 89 of these pilots so selected, she learns that 48 are more than 40 years of age. Construct an 85% confidence interval to estimate the population proportion of commercial airline pilots who are more than 40 years of age. B) Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Regina at rush hour by standing on the corner of Victoria Avenue and Albert Street and counting SUVs. You believe the figure is no higher than 0.40. If you want the error of the confidence interval to be no greater than 0.03, how many cars should you randomly sample? Use a 90% level of confidence.

Suppose that in a recent poll, 550 of the 915 randomly selected U.S. adults agreed with the statement “social media sites like Facebook and Twitter do more to divide the country” (as opposed to unite the country, or neither). a. Use this information to construct a 90% confidence interval.
2. In a simple random sample of 1200 Americans age 20 and over, 138 of them were found to have Type I diabetes. Round all answers to three decimal places. a) Report a 95% confidence interval for the proportion of all Americans age 20 and over with diabetes. J b) According to the Centers for Disease Control and Prevention, nationally, 10.7% of all Americans age 20 and over have diabetes. Does the confidence interval you found support or refute this claim? Explain.

A study examined parental influence on teenagers' decisions to smoke. A group of students who had never smoked were asked about their parents' attitudes to smoking. The students were questioned two years later to see if they had started smoking. The study found that, of the 287 students whose parents disapproved, 58 became smokers. Of the 48 students with lenient parents, 11 smoked. Complete parts a through c below. a) Create a 95% confidence interval for the difference between the proportion of children with lenient parents who later smoked, p1, and the proportion of children with disapproving parents who later smoked, p2. The confidence interval for p1−p2 is −0.101negative 0.101,0.1550.155. (Round to three decimal places as needed.) b) Interpret your interval in this context. Select the correct choice below and fill in the answer boxes within your choice. (Round to one decimal place as needed.) A. There is 95% confidence that the proportion of teens…
