Previously I required that you do all calculations without using Excel or Statistical software, using only a simple calculator. I did that to teach you critical thinking and attention to detail. Through this method, you have learned a lot and have gained confidence in dealing with mathematical formulas. However, for this assignment, you will obtain experience in using Statistical Software for your calculations. You will use Stratgraphics Stratus, a free online statistical package (httqulwwwstatgraphicsstratus.com(}. You will still need to follow the same processes and steps as outlined by the formula sheet for this design with the only difference being that Statgraphics will do your calculations for you. lhaye provided a step by step guide for using Statgraphics Stratus with this assignment. The statistical analysis and decision-making based on the data outcome will still be your own for the following research design. Siegel (1990) found that elderly people who owned dogs were less likely to pay visits to their doctors after upsetting events than were those who did not own pets. Similarly, consider the following hypothetical data. A sample of elderly dog owners is compared to a similar group [in terms of age and health) who do not own dogs. The researcher records the number of visits to the doctor during the past year for each person. Is there a significant difference in the number of doctor visits between dog owners and non-dog owners? Use a = 0.05. The data are included in Excel Data File #1. a. Is the research question directional or non-directional? Will this be a one-tail or two-tailed test? Please draw a full diagram of your research study including the two explanations of your data. b. Determine the critical t yalue(s}. Draw a graph to indicate the critical t yalue(s}, along with the high and low probability regions. c. Use Statgraphics Stratus to determine your calculated t yalue. Follow the Statgraphics guide which i have provided. What is the calculated t value? Copy the full page of the Statgraphics statistical analysis. d. Make a decision about the null hypothesis. e. Write the professional report ofthe results of your analysis. f. Submit all work to the assignment portal
