A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 743 women and 713 men were independently and randomly selected, and that 383 women and 282282 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2 )? Use a significance level of α=0.1 for the test. Step 1...

Back in the 1970s it was estimated that about 10% of Americans hunt. However, many of those close to the hunting sport believe there is a decline in the percentage of those that hunt now. A recent study by the US Fish and Wildlife Services found that of the 346 Americans surveyed, 53 of them say they hunt. Using a significance level of 0.05, test the claim that the proportion of American hunters now is less than what it was...

In a previous poll, 36% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 378 of 1108 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased?...

In a survey of 1,005 adult Americans, 45.7% indicated that they were somewhat interested or very interested in having web access in their cars. Suppose that the marketing manager of a car manufacturer claims that the 45.7 % based only on a sample and that 45.7% is close to half, so there is no reason to believe that the proportion of all adult Americans who want car web access is less than 0.50. s the marketing manager correct adult Americans....
