Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 95 politically conservative voters, r1 = 18 responded yes. Another random sample of n2 = 83 politically moderate voters showed that r2 = 21 responded yes. Does this information indicate that the population proportion of conservative voters inclined to spend more federal tax money on funding the arts is less than the proportion of moderate voters so inclined? Use α = 0.05.
What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.)
(c) Find (or estimate) the P-value. (Round your answer to four decimal places.)

Generally speaking, would you say that most people can be trusted? A random sample of n1 = 255 people in Chicago ages 18-25 showed that r1 = 43 said yes. Another random sample of n2 = 270 people in Chicago ages 35-45 showed that r2 = 65 said yes.

Do you prefer paintings in which the people are fully clothed? This question was asked by a professional survey group on behalf of a national arts organization. A random sample of n1 = 56 people who are conservative voters showed that r1 = 43 said yes. Another random sample of n2 = 65 people who are liberal voters showed that r2 = 37 said yes. Does this indicate that the population proportion of conservative voters who prefer art with fully...

Adults randomly selected for a poll were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of the subjects surveyed, 308 were in favor, 294 were opposed, and 82 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin flip. Use a 0.01 significance level to test the claim that the...

Prior to a local election, you would like to estimate the percentage of voters that are in favor of a 4% increase in gasoline sales tax in order to generate enough revenue for street repair. You decide to take a random sample of 400 local voters to see if at least 60% of voters support this initiative. Use this information to answer question 1a to 1e. (Hint: recall that for a Bernoulli random variable, the standard deviation is p(1 –...
