Data from the Bureau of Labor Statistics indicates that in a certain month, 35.2% of the labor force had a high school diploma or fewer years of education, 23.6% hadsome college or an associate's degree, and 41.2% had a bachelor's degree or more education. Of those with a high school diploma or fewer years of education, 6.5%were unemployed. Of those with some college or an associate's degree, 5.1% were unemployed, and of those with a bachelor's degree or more education, 4.2% wereunemployed. Find the probability that a randomly chosen labor force participant has some college or an associate's degree given that he or she is unemployed......The probability is(Type an integer or decimal rounded to three decimal places as needed.)

The North American Free Trade Agreement (NAFTA) enacted in 1994 is a trilateral trade agreement signed by the United States, Canada and Mexico. This trade agreement has been controversial since its inception and Americans remain split on the issue. In a Gallup Poll conducted February 1-5, 2017, 448 out of 973 randomly selected Americans aged 18 or older stated that they believed that NAFTA was bad for the United States. a. Find the point estimate for the proportion of Americans who believe that NAFTA was bad for the United States. Round your answer to 4 decimal places. b. Find the margin of error for a 95% confidence interval. Round your answer to 4 decimal places. c. Construct the 95% confidence interval for the proportion of Americans who believe that NAFTA was bad for the United States. Enter your answer as an open interval of the form (a,b) and round to 3 decimal places. d. Can you conclude that more than half of Americans believe that NAFTA was bad for the United States? No, the…

One strategy that may have an impact on employee retention, turnover and engagement is a successful employee recognition program. Surveying small organizations, those with 500 to 2,499 employees, and large organizations, those with10,000 or more employees, a survey organization showed that 323 (78%) of the 414 small organizations have employee retention programs as compared to 171 (87%) of the 196 large organizations. a. Determine the zstat, and the p-value. b.Determine the critical values and a conclusion c. Construct a 95% confidence interval estimate of the difference between the two population proportions.

A friend of yours tells you that they heard that 65% of all college athletes end up losing a finger or toe in their college athletic career. You're highly skeptical of this, but your not sure if that percentage is an over exageration or an under exageration. You survey 101 former student-athletes and find that 60 of them lost a digit during their college athletic career. Is this enough evidence to conclude that the true percentage of student-athletes that lose a digit during their collegiate career is really different from 65%?
1. The percentage of 12- to 17-year-olds who reported talking at least once in the past year with their parents about the dangers of drug, tobacco, or alcohol is 60% nationally. A state youth council believes this proportion is higher in their state, where there has been an intense media campaign about this issue. A survey of randomly chosen students from across the state shows 1032 of 1642 students reporting they are having these conversations with their parents. Is there evidence that the percent of students using drugs, tobacco or alcohol in this state is above the national rate?
1.76 Peace Corps Volunteers. The Peace Corps is an indepen- dent U.S. government agency that provides trained volunteers for countries requesting assistance. According to Peacecorps.org, as of September 2012, volunteers currently serve in about 76 different host countries. The average age of a volunteer is about 28 years old. The following table reports the percentage of total volunteers serving by geographic region. Percent of volunteers Region Africa 43% Latin America 21% Eastern Europe/Central Asia 15% Asia 10% Caribbean 4% North Africa/Middle East 4% Pacific Islands 3% a. Use the table to design a procedure for obtaining a stratified sam- ple (with proportional allocation) of 50 Peace Corps volunteers. b. If stratified random sampling with proportional allocation is used to select the sample of 50 Peace Corps volunteers, how many would be selected from the Caribbean?
For a study that has one independent variable with three levels and 4000 participants per level, what is the recommended maximum number of analyses (comparisons or contrasts) to plan? (hint: This is the same as the number of independent research questions that can be asked) a. One, because this is the number of independent variables. b. Two, because this is one less than the number of groups. c. 11999, because this is one less than the number of participants. d. Any number...as long as the analysis is pre-registered there is nothing to worry about.

3. A sociologist studying freshmen at a major university carried out a survey, asking (among other questions) how often students went out per week, how many hours they studied per day, and how many hours they slept at night. Students will often overstate the number of hours studied, because they do not want to admit to not studying enough. This type of distortion is called: a. false answer. b. non-response bias. c. undercoverage bias. d. response bias.
