1000 randomly selected Americans were asked if they believed the minimum wage should be raised. 600 said "yes." What is the 99% confidence interval for the proportion of Americans who believe that the minimum wage should be raised?

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)

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned.   Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.”    Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations.   1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.

Fear of the dark is quite common among children. However, what about adults? One polling agency released the results of a survey that asked people over 30 years old if they keep the lights on at night. Among 452 respondents, 34% indeed leave the light on when going to sleep. What does this margin of error tell you about the percentage of adults who keep the lights on at night? We can be 95% confident that somewhere between   % and   % of adults keep the lights on at night.

In a recent poll, 240 people were asked if they liked dogs, and 47% said they did. Find the margin of error of this poll, at the 90% confidence level.Give your answer to three decimals

Online News In a Harris poll of 2036 adults, 40% said that they prefer to get their news online. Construct a 95% confidence interval estimate of the percentage of all adults who say that they prefer to get their news online. Can we safely say that fewer than 50% of adults prefer to get their news online?

In a recent survey of 1264 US adults, 26.6% said they had seen a ghost.  What is the LOWER endpoint of a 98% confidence interval for the population proportion? What is the UPPER endpoint of a 98% confidence interval for the population proportion?  Answers should be decimals (not percentages).
