Assignment 1: Testing Hypotheses for MeansThis week you have explored three different approaches to t tests. By this point, you know that each test has assumptions about the data and type of research questions it can answer. For this Assignment, you will be provided with three scenarios. As you read the scenarios, be sure and think about aligning the appropriate t test with the question. Consider whether the data are independent samples and if two samples are being compared.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 testPaired sample t testOne sample t testBased 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.By Day 7Submit Assignment 1: Testing Hypothesis for a Mean.

Project Part 3 - Confidence Intervals Based on the class sample, you will create a 95% confidence interval for the mean age and the proportion of males in the population of all online college students. Using the same sheet as part 2, answer the following in the “week 5” tab: For the average age, form a 95% confidence interval: What distribution should be used?What is the critical value?What is the error bound?What is the lower bound?What is the upper bound? For the proportion of males, form a 95% confidence interval: What distribution should be used?What is the critical value?What is the error bound?What is the lower bound?What is the upper bound?

You are provided with two options for your course project below. Select ONE of the options below for your analysis.Option 1 allows you to analyze job salaries for the state of Minnesota.Option 1 ScenarioOption 1 Data SetOption 2 allows you to analyze the ages of infectious disease patients at NCLEX Memorial Hospital. Option 2 ScenarioOption 2 Data SetReview each scenario and data set carefully and choose which scenario you would like to work with. Begin Phase 1 of your analysis by including the following information:Introduce your scenario and data set.Provide a brief overview of the scenario you are given above and the data set that you will be analyzing.Classify the variables in your data set.Which variables are quantitative/qualitative?Which variables are discrete/continuous?Describe the level of measurement for each variable included in your data set.Discuss the importance of the Measures of Center and the Measures of Variation.What are the measures of center and why are they important?What are the measures of variation and why are they important?Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic. MeanMedianMode Midrange RangeVarianceStandard DeviationConclusionRecap your ideas by summarizing the information presented. This assignment should be formatted using APA guidelines and a minimum of 2 pages in length.
