Researchers conducted a survey to examine the difference between the proportion of females who vote and the proportion of males who vote. They found that 85 of 200 males voted whereas 124 of 220 females voted. Which of the following represents the 95% confidence interval for the difference of proportions females males in this case? O (0.225, 0.402) (0.095, 0.282) O (0.044, 0.233) (0.050, 0.147)

Through polling, it was estimated that the percent of people who will vote for a particular candidate in an upcoming election is 36.2%. If the margin of error is 3.5, give the confidence interval for the percentage of people who will vote for the candidate in the upcoming election.% to %

A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)

in a public opinion pool 1000 randomly selected persons were asked whether they would vote for candidate x in the next election and 357 replied "yes". the 90% confidence interval for the proportion of the population who would answer "YES" to the same question is?

Most married couples have two or three personality preferences in common. A random sample of 370 married couples found that 130 had three preferences in common. Another random sample of 572 couples showed that 234 had two personality preferences in common. Let p1 be the population proportion of all married couples who have three personality preferences in common. Let p2 be the population proportion of all married couples who have two personality preferences in common.   (a) Find a 99% confidence interval for p1 – p2. (Use 3 decimal places.) lower limit   upper limit

Ten engineering schools in the US were surveyed. the sample contains 250 electrical 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. Select one: O a. (0.02, 0.16) Ob. (0.01, 0.17] O. (0.04, 0.14) O d. [0.03, 0.15]
