Chapter 7: Problem 69

Exercises 69 to 72 refer to the following setting. In the language of government statistics, you are "in the labor force" if you are available for work and either working or actively seeking work. The unemployment rate is the proportion of the labor force (not of the entire population) who are unemployed. Here are data from the Current Population Survey for the civilian population aged 25 years and over in a recent year. The table entries are counts in thousands of people. Unemployment \((1.1)\) Find the unemployment rate for people with each level of education. How does the unemployment rate change with education?

Short Answer

Expert verified
Calculate the unemployment rate for each education level, and observe that unemployment generally decreases with higher education levels.

Step by step solution

01

Understand the Data

We need to find the unemployment rate among people with different levels of education. We understand that the unemployment rate is calculated as the number of unemployed people divided by the total number of people in the labor force for each education level.
02

Gather Necessary Data

Identify the data columns: Total labor force, Employed people, and Unemployed people, for each education level, using the available data. Ensure you have these counts for four groups: less than high school, high school graduates, some college, and college graduates.
03

Calculate Unemployment Rate

For each education level, apply the formula: \( \text{Unemployment Rate} = \frac{\text{Unemployed}}{\text{Total Labor Force}} \times 100 \). This will give us the unemployment rate in percentage for each education group.
04

Analyze Findings

After computing the unemployment rate for each level of education, compare these rates to see how unemployment changes with increasing level of education. Typically, higher educational attainment associates with lower unemployment rates.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Labor Force Participation
Understanding labor force participation is crucial when discussing unemployment statistics. The labor force includes all individuals aged 15 and above who are either working or actively looking for work. Being in the labor force means you're either employed or unemployed but seeking employment.

It excludes those who are not seeking work, such as students, retirees, and stay-at-home parents. The participation rate is a vital statistic that reflects the active portion of the population ready to contribute to the economy. Key points include:
  • The labor force is dynamic, with individuals entering and leaving for various reasons.
  • A higher labor force participation rate suggests a robust economy with more individuals engaging in work-related activities.
Evaluating labor force participation helps understand the economic health and the availability of job opportunities in a region.
Educational Attainment
Educational attainment plays a significant role in shaping employment opportunities and outcomes. It refers to the highest level of education a person has completed. Generally, data indicates that higher educational attainment correlates with lower unemployment rates. Here are some insights:
  • Graduating from high school provides a fundamental level of qualification helpful in securing various employment opportunities.
  • Further education, such as acquiring a college degree, often opens doors to more job prospects and typically results in better job security and potential for advancement.
Studying employment rates across different educational levels can reveal the value of education in reducing unemployment and increasing participation in the workforce.
Statistical Analysis
Statistical analysis is a method used to collect, review, and interpret data. In the context of unemployment rates, this involves using statistical tools to determine how different levels of education affect employment status.Common practices include:
  • Analyzing data sets that encapsulate employment statistics segmented by education level.
  • Applying the unemployment rate formula: \( \text{Unemployment Rate} = \frac{\text{Unemployed}}{\text{Total Labor Force}} \times 100 \).
  • Comparing the results across varied educational backgrounds to draw meaningful conclusions.
These analyses can inform policies and initiatives aimed at reducing unemployment through educational programs and other interventions.
Employment Statistics
Employment statistics offer a snapshot of the job market and economic conditions. They include data on employment, unemployment, labor force participation, and other related metrics.

Accurate employment statistics are critical for policymakers and economists to understand and address employment issues. Components include:
  • Total employment figures, representing those currently working.
  • Unemployment figures, representing those who are job-seeking.
  • Segmented statistics that reveal differences based on factors like educational attainment.
Tracking these numbers over time allows for monitoring trends and helps in responding to economic shifts, ensuring a properly functioning labor market.

Exercises 69 to 72 refer to the following setting. In the language of government statistics, you are "in the labor force" if you are available for work and either working or actively seeking work. The unemployment rate is the proportion of the labor force (not of the entire population) who are unemployed. Here are data from the Current Population Survey for the civilian population aged 25 years and over in a recent year. The table entries are counts in thousands of people. Unemployment \((5.3)\) If you know that a randomly chosen person 25 years of age or older is a college graduate, what is the probability that he or she is in the labor force? Show your work.

ACT scores The composite scores of individual students on the ACT college entrance examination in 2009 followed a Normal distribution with mean 21.1 and standard deviation 5.1 (a) What is the probability that a single student randomly chosen from all those taking the test scores 23 or higher? Show your work. (b) Now take an SRS of 50 students who took the test. What is the probability that the mean score \(\overline{x}\) of these students is 23 or higher? Show your work.

Who owns a Harley? Harley-Davidson motorcycles make up 14\(\%\) of all the motorcycles registered in the United States. You plan to interview an SRS of 500 motorcycle owners. How likely is your sample to contain 20\(\%\) or more who own Harleys? Follow the four-step process.

A newborn baby has extremely low birth weight \((\mathrm{ELBW})\) if it weighs less than 1000 grams. A study of the health of such children in later years examined a random sample of 219 children. Their mean weight at birth was \(\overline{x}=810\) grams. This sample mean is an unbiased estimator of the mean weight \(\mu\) in the population of all ELBW babies, which means that (a) in all possible samples of size 219 from this population, the mean of the values of \(\overline{x}\) will equal 810 . (b) in all possible samples of size 219 from this population, the mean of the values of \(\overline{x}\) will equal \(\mu .\) (c) as we take larger and larger samples from this population, \(\overline{x}\) will get closer and closer to \(\mu\) (d) in all possible samples of size 219 from this population, the values of \(\overline{x}\) will have a distribution that is close to Normal. (e) the person measuring the children's weights does so without any systematic error.

Multiple choice: Select the best answer for Exercises 43 to \(46,\) which refer to the following setting. The magazine Sports Illustrated asked a random sample of 750 Division I college athletes, "Do you believe performance- enhancing drugs are a problem in college sports?" Suppose that 30\(\%\) of all Division I athletes think that these drugs are a problem. Let \(\hat{p}\) be the sample proportion who say that these drugs are a problem. The sampling distribution of \(\hat{p}\) is approximately Normal because (a) there are at least 7570 Division I college athletes. (b) \(n p=225\) and \(n(1-p)=525\) (c) a random sample was chosen. (d) a large sample size like \(n=750\) guarantees it. (e) the sampling distribution of \(\hat{\rho}\) always has this shape.
