The National Study of the Changing Work Force has just completed an extensive survey of 2958 wage and salaried workers on issues ranging from relationships with their bosses to household chores. The data were gathered through hour-long telephone interviews with a nationally representative sample (The Wall Street Journal). In response to the question “What does success mean to you?” 1538 responded, “Personal satisfaction from doing a good job.”
Based on your professional skills in statistical analysis, you have just been hired to help with an analysis and interpretation of this survey.
If p be the population proportion of all wage and salaried workers who would respond the same way to the stated question, what would be the 80% (or 90% or 95% or 99%) confidence interval for p.
Make sure that you show your computations.
