The U.S. Census Bureau conducts annual surveys to obtain information on the percentage of the voting-age population that is registered to vote. Suppose that 713 employed persons and 613 unemployed persons are independently and randomly selected and that 338 of the employed persons and 244 of the unemployed persons have registered to vote. Can we conclude that the percentage of employed workers ( p1 ), who have registered to vote, exceeds the percentage of unemployed workers ( p2 ), who have registered to vote? Use a significance level of α=0.1 for the test.
Step 1 of 6 :
State the null and alternative hypotheses for the test.
Step 2 of 6 :
Find the values of the two sample proportions, pˆ1p^1 and pˆ2p^2. Round your answers to three decimal places.
Step 3 of 6 :
Compute the weighted estimate of p, p‾p‾. Round your answer to three decimal places.
Step 4 of 6 :
Compute the value of the test statistic. Round your answer to two decimal places.…
Jury Census data for a certain county show that 19%of the adult residents are Hispanic. Suppose 72 peopleare called for jury duty and only 9 of them are Hispanic.Does this apparent underrepresentation of Hispanics callinto question the fairness of the jury selection system?Explain.
A survey of 1000 adult Internet users found that 55% of 18-to 24- year –olds, 60% of 25-to 34- year –olds, 64% of 35-to 49- year –olds, 78% of 50 – to- 64 year-olds, and 85% of 65 – to- 89-year-olds opposed online ads tailored to their individual interests. Supposed the survey was based on 200 respondents in each of the five age groups.
Construct the contingency table based on the information given.
Compute the expected frequencies for each cell.
Compute. Is there evidence of a significance difference among the age groups with respect to the proportion who preferred to use media social as the medium of communication? (Use α=0.01)

The sample included 262 18- to 29-year olds. a) Do you expect the 90% confidence interval for the true proportion of all 18- to 29-year olds who think the U.S. is ready for a woman president to be wider or narrower than the 90% confidence interval for the true proportion of all U.S. adults? b) Construct a 90% confidence interval for the true proportion of all 18- to 29-year olds who believe the U.S. is ready for a woman president. a) The 90% confidence interval for the true proportion of 18- to 29-year olds who think the U.S. is ready for a woman president will be about twice as wide as the 90% confidence interval for the true proportion of all U.S. adults who think this. b) The 90% confidence interval is ( %. %).…arrow_forwardSuppose that a technology task force is being formed to study technology awareness among instructors.
