Respond to the following in a minimum of 175 words: 

Suppose that we wish to assess whether more than 60 percent of all U.S. households in a particular income class bought life insurance last year. That is, we wish to assess whether p, the proportion of all U.S. households in the income class that bought life insurance last year, exceeds .60. Assume that an insurance survey is based on 1,000 randomly selected U.S. households in the income class and that 640 of these households bought life insurance last year.

a)   Assuming that p equals .60 and the sample size is 1,000, what is the probability of observing a sample proportion that is at least .64?

b)  Based on your answer in part a, do you think more than 60 percent of all U.S. households in the income class bought life insurance last year? Explain.

Social Movements that Defined a Decade

/in /by

As the United States entered the 1980s, race and gender issues continued to take center stage, but other concerns also became the focus of many grassroots activists. From HIV/AIDS awareness to the environment, activists challenged local, state, and federal authorities and big business to improve the way of life for humans, animals, and the earth. In many cases, their activism not only raised awareness, but also spurred increasing government intervention.

For this week’s Discussion, you will identify a social movement that you believe defined a decade.

In preparation for this Discussion:

  • Review this week’s Learning Resources. With these issues providing context for this time period, consider the many social change movements and issues that emerged or escalated during the 1980s and 1990s, including:
    • Quality of education (A Nation at Risk)
    • Access to health care
    • War on drugs
    • Gender inequalities (the feminization of poverty)
    • Ongoing civil rights movements
    • Gay rights
    • AIDS activism
    • Environmental issues
    • Urban and rural poverty
  • Using the Walden Library and other reliable resources, research these varied issues and movements to gain an overview of the breadth of concerns that impacted Americans in the 1980s and 90s. Consider the background of each and the populations that were impacted.
  • What changes have occurred regarding these issues?
  • What impact, if any, did these movements have on the United States and the world?
  • With these considerations in mind, select a movement that you think defined either the 1980s or the 1990s.

With these thoughts in mind:

 Question 1

Post a response to the Discussion Spark post. Your response should contain at least two significant paragraphs. Identify a historical social, political, or economic issue from the 1980s or 1990s that continue to adversely affect the United States today. Has a movement emerged to successfully address this issue? If yes, what impact has it had? If no, why do you think that no substantial movement has evolved?  continue to adversely affect the United States today. Has a movement emerged to successfully address this issue? If yes, what impact has it had? If no, why do you think that no substantial movement has evolved?

 

 Question 2

Post a 2- to 3-paragraph explanation of how one social movement defined either the decade of the 1980s or the decade of the 1990s. Include in your posting a brief description of the movement, a rationale for its relevance, and the impact that this movement has had on the both the United States and the world
