If there are 65 successes of 150 trials in the one group, and 115 successes of 200 in another, are the proportion of successes significantly different? Use ?=0.05. They are not significantly different, because the interval boundaries have the same signs. None of these. They are significantly different, because the interval boundaries have the same signs. They are significantly different, because zero is contained in the confidence interval. They are significantly different, because the interval boundaries have different signs. They are not significantly different, because the interval boundaries have different signs.

1st Group: x1=65n1=150 2nd Group: x2=115n2=200 Significance level, α=0.05

A marketing survey involves product recognition in New York and California. Of 679 New Yorkers surveyed, 256 knew of the product while 208 of 631 Californians knew of the product. Construct a 99% confidence interval for the difference between the two population proportions, P₁-P₂ (where p₁ is the proportion of New Yorkers who knew of the product, and P₂ is the proportion of Californians who knew of the product). Give your answers as decimals, rounded to 3 places after the decimal point (if necessary). 99% confidence interval for P₁ - P2:

Let's say you survey a random sample of people. You find that 53% prefer apples over oranges. You make a 90% confidence interval for the proportion of people who prefer apples. The resulting confidence interval is: 0.448 to 0.612 Based on this interval, assess the following statement: There is a 90% probability that the proportion of people who prefer apples over oranges is between 0.448 and 0.612. is it true or false

Kit and Casey are each attempting to estimate the proportion of college students who can play at least one musical instrument. They each survey a different random sample of college students, and in each sample, the proportion who can play at least one musical instrument is 0.35. Kit and Casey each use their sample data to construct a confidence interval. Kit's interval is from 0.308 to 0.372 and Casey's interval is from 0.318 to 0.382. One of these intervals was computed correctly, but the other was not. Which interval must be incorrect? O Kit's interval must be incorrect. O It's impossible to answer this question without knowing the sample sizes. O It's impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval. O Casey's interval must be incorrect. O It's impossible to answer this question without knowing the level of confidence used for each interval.
Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
The Athletics Department at a high school is interested in the difference in the run times between 11th and 12th grade students. Suppose the 11th grade students make up the first sample while the 12th grade students make up the second.Using a confidence level of 95%, the confidence interval found was (−1.8,2.9)(-1.8,2.9).Which of the following is the correct interpretation? We are 95% confident that the run times of the 11th grade students are, on average, faster than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, slower than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, about the same as those of the 12th grade students.
A beverage company would like to determine if their drink is preferred to a rival company’s drink. They perform an experiment with 150 randomly selected individuals and have them taste test the two different drinks in a controlled environment so that each person's preference is independent of others. A 90% confidence interval for the proportion preferring their drink is (0.453, 0.587). Which of the following is the correct interpretation of this confidence interval? 90% of all consumers prefer this beverage company’s drink to their rival’s between 45.3% and 58.7% of the time. We’re 90% confident that between 45.3% and 58.7% of all consumers would prefer this beverage company’s drink to their rival’s drink. We’re 90% confident that there’s a 45.3% to 58.7% chance that a randomly selected person would prefer this beverage company’s drink to their rival’s drink.
