What is a hypothesis test? Why do we need to use them to make
decisions about relating sample results to the population; why can’t we just
make our decisions by the sample value?
Guided Response: Review several of your classmates’ posts. Respond to
at least two classmates by commenting on the potential differences in the
results and how that might affect decision making.
Variation exists in virtually all parts of our lives. We often see variation in
results in what we spend (utility costs each month, food costs, business
supplies, etc.). Consider the measures and data you use (in either your
personal or job activities). When are differences (between one time period
and another, between different production lines, etc.) between average or
actual results important? How can you or your department decide whether
or not the observed differences over time are important? How could using
a mean difference test help?
Guided Response: Review several of your classmates’ posts. Respond to
at least two classmates and comment on the use of the test.

MM 305 Purdue University Global Unit 10 Checking for Quality Discussion
Topic: Checking for QualityScenario: A venture capitalist has just given you several million dollars to develop your dream product! Explain in detail what this product is and why people would buy it. (Think Steve Jobs and the iPhone - did people really think we needed “smartphones” back in 2007?)Main Post: Now your dream product has gone into production and the manager is asking you, as the statistical expert, to use statistical methods to ensure quality control. See Example (attached) and DB starter video in Unit 10 LiveBinder.1. You will generate a random dataset of N samples of defective proportions by completing the following steps:a) You will start with a random number by combining the last 2 digits of the year in which you were born plus the day of the month in which you were born. For example, if you were born October 3, 1990, your number would be 90 + 3 = 93. (If your number exceeds 100, subtract 100 from the total.) Call this X and it will seed your random number generation.b) Choose a number of samples, N. (N should be between 5 and 10 samples.)c) In Excel, type =RAND()*X in a cell. Repeat N times. This will generate the proportion of defective products (out of 100) for your N samples.2. Use Excel to create a p-chart for a sample size, 100, and the number of samples, N.3. Write a professional memo to your business/company owner describing the production quality so far and prioritizing any control measures necessary to guarantee high quality products. Address the following items and questions in your professional memo:Describe your product, its use, and societal value. (Humor is encouraged.)Share and summarize your p-chart.What is your Lower Control Limit (LCL) and Upper Control Limit (UCL)?Is the product in control? If not in control, what sample(s) was outside of the limits, i.e., below LCL or above UCL?What measures could be taken now to address the data points that out of control?What recommendations would you suggest to optimize quality in future production?

Walden Relationship Between Trust in Police and Presence of Democracy in Africa Paper
For this Assignment, you will consider three different scenarios. For Each of these scenarios include a research question. You will examine each scenario, choose a categorical data analysis and run a sample test.

Next, review the Chi Square Scenarios found in this week’s Learning Resources and consider each research scenario for this Assignment.Based on the dataset you chose and for each research scenario provided, using the SPSS software, choose a categorical data analysis and run a sample test.Once you perform your categorical data analysis, 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 1- to 2-paragraph analysis of your categorical data results for each research scenario. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be. Scenarios Results of your literature review conclude that trust in the police is an integral part of any democracy. You wish to test whether a relationship between trust in the police and presence of democracy (measured with dichotomous variable) exists in Africa.
