A newsgroup is interested in constructing a 95% confidence interval for the difference in the proportions of Texans and New Yorkers who favor a new Green initiative. Of the 596 randomly selected Texans surveyed, 412 were in favor of the initiative and of the 580 randomly selected New Yorkers surveyed, 473 were in favor of the initiative.a. With 95% confidence the difference in the proportions of Texans and New Yorkers who favor a new Green initiative is between (BLANK #) (round to 3 decimal places) and (BLANK #) (round to 3 decimal places).b. If many groups of 596 randomly selected Texans and 580 randomly selected New Yorkers were surveyed, then a different confidence interval would be produced from each group. About (BLANK #) percent of these confidence intervals will contain the true population proportion of the difference in the proportions of Texans and New Yorkers who favor a new Green initiative and about (BLANK#) percent will not contain the true population difference in…
Suppose taxi fares from Logan Airport to downtown Boston is known to be normally distributed and a sample of seven taxi fares produces a mean fare of $22.31 and a 95% confidence interval of [$20.5051, $24.2091]. Which of the following statements is a valid explanation of the confidence interval. A) 95% of all taxi fares are between $20.51 and $24.21. B) We are 95% confident that a randomly selected taxi fare will be between $20.51 and $24.21. C) The mean amount of a taxi fare is $22.31, 95% of the time. D) We are 95% confident that the average taxi fare between Logan Airport and downtown Boston will fall between $20.51 and $24.21.

Ten engineering schools in a country were surveyed. The sample contained 225electrical engineers, 80 being women; 175 chemical engineers, 40 being women. Compute a 90% confidence interval for the difference between the proportions of women in these two fields of engineering. Is there a significant difference between the two proportions? Let p1 be the population proportion of electrical engineers that are women in the schools that were surveyed and let p2 be the population proportion of chemical engineers that are women in the schools that were surveyed. The 90% confidence interval is nothing<p1−p2<nothing. (Round to three decimal places as needed.)

From a random sample of 185 children from school G, 108 indicated they wanted to study science in college. From a different random sample of 165 children from school H, 92 indicated they wanted to study science in college. Assuming all conditions for inference are met, which of the following is closest to the standard error for a confidence interval for the difference in population proportions between the two schools of children who want to study science in college?
For a study on the current trend in the design of social robots, researchers obtained a random sample of 103 social robots through a Web search and determined that 63 were designed with legs, but no wheels. Complete parts a and b. a. Find a 90% confidence interval for the proportion of all social robots designed with legs, but no wheels. Interpret the result.

The Virginia Department of Environmental Quality (VDEQ) uses probabilistic monitoring to regulate the water quality of streams in the Commonwealth of Virginia. Of the 85 Eastern Virginia Sites (group 1), 17 do not meet minimum requirements. Of the 80 units sampled in Western Virginia Sites (group 2), 24 do not meet minimum requirements. Assume the data can be treated as independent simple random samples. The hypotheses to test that the proportions of streams that fail to meet minimum requirements in the two areas are equal or not is O Ho: P1 P2 vs. Ha: P1 P2 O Ho: P1 P2 vs. Ha: P₁ P2 P2 vs. Ha: P₁ = P2 O Ho: P1 O Ho: P1 P2 Vs.
