A survey of 500 randomly selected students was taken and 200 responded that they favor candidate Z for class president (p ₁ = 0.4). Just before the election, another survey of 700 students was taken and 450 students responded that theyfavor candidate Z (P 2 = 0.6429). A 98% two-proportion z confidence interval for the true difference between p ₁ and p 2 was found to be (-0.3090, -0.1767). What is the meaning of the interval in the context of the problem?O There has been no change in support for the candidate.O There has been a substantial drop in support for the candidate.O There has been a substantial gain in support for the candidate.O It is probable for the candidate to get most of the votes because support has risen more than 50%.O It is not probable for the candidate to get most of the votes because the interval is negative.

The confidence interval given is (-0.3090, -0.1767)This interval represents the range within which…

A survey was conducted of visitors to the Jakarta Fair. For this reason, two groups of samples were taken. The first sample was 500 visitors for women and when they were asked 325 people said they were satisfied with the exhibition at the Jakarta Fair, while the second sample consisted of 700 visitors for gentlemen and 300 of them said they were not satisfied with the exhibition at the Jakarta Fair. the Jakarta Fair. Make a 95% confidence interval to estimate how much the difference between the two populations of visitors who are satisfied with the exhibition at the Jakarta Fair?

A nationwide poll of 2,525 adults estimated with 95% confidence that the proportion of Americans who support health care reform is 0.78 +/- 0.0162. A member of Congress thinks that 95% confidence isn't enough. He wants to be 99% confident. How would the margin of error of a 99% confidence interval based on the same sample size compare with the 95% interval? O It would be larger, because higher confidence results in a larger margin of error. O It would be the same, because the sample size is the same. O Can't tell, because margin of error depends on the size of the population. O Can't tell, because margin of error varies from sample to sample. O It would be smaller, because higher confidence results in a lower margin of error.
A random sample of Roosevelt High School students was asked if they prefer taking notes on a computer or using a paper and pencil. Of the 180 students who were surveyed, 75 said they preferred using the computer. The resulting 99 percent confidence interval for the proportion of students who prefer taking notes on the computer was (0.322, 0.511). The school newspaper ran a story saying that less than half of the student body prefers taking notes on a computer. Based on the interval, is the newspaper justified in its statement? Yes. The sample proportion of students who prefer taking notes on their computer was 0.417, which is less than 0.5. Yes. Since nearly the entire confidence interval contains values less than 0.5, we can be certain that less than 50% of students prefer using a computer for notes. No. Since the interval contains values above 0.5, it is plausible that more than 50% of students prefer using a computer for notes. No. Since the interval contains values above 0.5, we…
