In a survey conducted in August, 2017, a random sample of 2,752
U.S. adults were asked whether they had visited a public library in
the previous 12 months. The results of this survey are shown in the
two-way table below, stratified by gender. Conduct a hypothesis test
on this data, using a 10% significance level, to test the claim that
the true proportion of U.S. adult males who visited a public
library in the previous 12 months differs from the proportion of
U.S. adult females who did so. Calculate a 90% confidence interval,
using a bootstrap distribution, for the difference in
proportions.

In a 2012 survey, Gallup asked a random sample of U.S. adults if they would prefer to have a job outside the home, or if they would prefer to stay home to care for the family and home. Of the 504 males they surveyed, 391 said that they would prefer to have a job outside of the home. Of the 473 females they surveyed, 254 said that they would prefer a job outside of the home.

1, In 1943, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1100 adults surveyed, 385 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 363 indicated that they were total abstainers. Complete parts (a) and (b) below. (a) Determine the sample proportion for each sample. The proportions of the adults who took the 1943 survey...

Invest in science ~ The Pew Research Center conducted a survey of U.S. adults in 2019 to determine how American citizens feel about whether federal government should increase spending for scientific research. In the study, there were 711 Democrats and 647 Republicans. According to the survey, 436 Democrats and 270 Republicans said they are in favor of increased spending for scientific research. We want to estimate the actual difference between the proportions of Democrats and Republicans who favor increased spending...
A Gallup survey of 1,001 randomly selected U.S. adults conducted May 2011, asked “In your opinion, which one of the following is the main reason why students get education beyond high school?” Fifty three percent chose “to earn more money.” Based on these data, I found the 95% confidence interval for the proportion of U.S. adults who choose “to earn more money” to be (0.499, 0.561). Explain in at least 1 sentence. TRUE/FALSE? Ninety-five percent of all U.S. adults are...
1. In an August 2012 Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12. The bootstrap distribution (based on 5,000 samples) is provided. a). Would it be appropriate to use the normal distribution to construct the confidence interval in this situation? Explain briefly. b). The standard error from the bootstrap distribution is SE = 0.016. Use the normal distribution...
6) Residence ~ A survey by the National institute of health asked a random sample of young adults aged 19-25 years the following question: Where do you stay most often currently?

Residence type Gender Female Male Parents' home 923 986 Another person’s place 144 132 Own place 1294 1129 Group quarters 127 119 If we want to assess whether there is a relationship between residence type and gender, then...
12. (8 pts) A survey of 1,000 randomly chosen U.S. adults asked whether the respondents thought that the manna eaten by the Israelites during their forty years of wandering in the desert was really popcorn. There were 70 people who said yes. Calculate a 95% confidence interval for the proportion of U.S. adults who believe the manna was really popcorn. Show your work.
In a survey of 230 males ages 20 to 24,44% were neither in school nor working. In a survey of 240 females ages 20 to 24, 46% were neither in school nor working. These samples are random and independent. At a = 0.10, can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school...
