testing hypothesis for means, writing homework help

1. As an international development researcher, you would
   like to know African Citizen’s perceptions about current levels of
   democracy. Your working hypothesis is that a series of reforms have
   increased African views of the level of democracy today. You do not have
   a good research design to compare attitudes before and after the
   reforms, but know that leaders and development experts would like to see
   a value of 6, on the scale of 1–10. Using the data from the 2015
   Afrobarometer, determine whether perceptions about current levels of
   democracy statistically differ from a value of 6. Please provide: a 1–2
   APA style paragraph statement that furnishes an answer to this question,
   note the relevant statistics, comment on meaningfulness and include
   your relevant SPSS output. 2. As an international development
   researcher, you have already tested whether perceptions about the
   current levels of democracy differ from a value of 6. Given recent
   social change movements in North Africa, you now want to determine
   whether there is a statistical difference in these perceptions between
   North Africa and Southern Africa. Using the data from the 2015
   Afrobarometer, please provide: a 1–2 APA style paragraph statement that
   furnishes an answer to this question, note the relevant statistics,
   comment on meaningfulness, and include your relevant SPSS output. 3.
   As an educational researcher, would like to know whether high school
   student’s perceptions about mathematical utility changed between their
   freshman and senior year. Each respondent is asked the same series of
   questions about the utility of mathematics in their future during their
   freshman and senior year. These questions are combined to form one
   variable of mathematical utility; higher values indicate higher levels
   of mathematical utility. Using the High School Longitudinal Survey,
   please provide: a 1–2 APA style paragraph statement that furnishes an
   answer to this question, note the relevant statistics, comment on
   meaningfulness, and include your relevant SPSS output.

To prepare for this Assignment:

• Review the Learning Resources and the media programs related to t tests.
• Also, review the t test scenarios found in this week’s Learning Resources and consider the three different approaches of t tests:
  • Independent sample t test
  • Paired sample t test
  • One sample t test
• Based
  on each of the three research scenarios provided, open the High School
  Longitudinal Study dataset or the Afrobarometer dataset from this week’s
  Learning Resources using SPSS software, then choose and run the
  appropriate t test.
• Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.

For this Assignment:

Write a 2- to 3-paragraph analysis of your t
test results for each research scenario and include the SPSS syntax and
output. Based on your results, provide an explanation of what the
implications of social change might be.

Use proper APA format, citations, and referencing for your analysis, research questions, and output.
