Two sample 2 Two Sample Hypothesis Testing Team A has decided to compare home values, based on distance. Both the numerical and verbal hypothesis will be based on the data table provided by Lind, Marchal, & Wathen, (2008). This team will determine if homes closer to the city center, 6-15 miles, are more affordable than home further from the city center, 16-28 miles. In order to make this determination, Team A will conduct the five-step hypothesis test (Doane & Seward, 2007). Following this series of tests, Team A will discuss their findings, and explain how these answers can be used to answer the research hypothesis question. The five steps mentioned earlier are as follows: 1. State research question 2. Specify the null and alternate hypothesis 3. Calculate test statistic 4. Compute probability of test statistic or rejection region 5. State conclusions The verbal hypothesis will now be converted into a numerical hypothesis: h : µ= 0 h : µ <> 0 The process of hypothesis testing is used to prove or disapprove the research question. By only allowing a strict marginal room for error, this team will use 5%, and reaching a correct decision based on statistical principles, researchers are able to conclude that result produced must
Two sample 3 be real. These five steps are composed of several decision factors that researchers need in order to answer any research question using an inferential statistic test. First step is to identifying the research problem. This should be stated in terms of a question, which will identify the population(s) of interest base on the interest of the researcher, the parameter(s) of the variable that is being research, and the hypothesized value of the parameter(s). This is the step in which researchers define what he or she is attempting to test,
