Buad 310 Case Analysis Instruction

6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

6. Although you are basically satisfied with the analysis thus far, you are concerned about the

Assignment 4: I developed a hypothesis to predict what effect an increase in island size will have on beak size and finch populations. I tested my hypothesis by leaving all other parameters at their default values. Selected the Island Size input and use the sliders to increase the size of either. Then I tested the effect of the parameters to influence population size and beak size by designing and running experiments to get my

4. Based on your analysis in (1) – (3) above, what is your overall conclusion regarding the

Exercises 12.17, 12.21, and 12.43 require the use of the “Regression” function within the Data Analysis menu in Excel. Refer to Appendix E12 for instructions on using Excel for these exercises.

6. Restate your predictions that were correct and give the data from your experiment that supports them. Restate your predictions

5) Graph the equation you wrote in step four superimposed over the original data. Comment on how well or how

7. The data set for this problem can be found through the Pearson Materials in the Student Textbook Resource Access link,

Problem 2.4: Consider the sample from a bank database shown in Figure 2.14; it was selected randomly from a larger database to be the training set. Personal Loan indicates whether a solicitation for a personal loan was accepted and is the response variable. A campaign is planned for a similar solicitation in the future, and the bank is looking for a model that will identify likely responders. Examine the data carefully and indicate what your next step would be.

You provided no discussion about TAXYPR, TGEG, and DMC in Table 4. How can you insert TGEG and DMC into the regression equation as explanatory variables?

1. Examine the data provided in Tables 3.1 and 3.2. Write a one page memo describing what the results show. Be certain to emphasize both the practical and statistical and statistical significance of the results. Also, be certain to note which of the predictors is most related to which of the relevant outcomes.

In the following discussion of how I performed each task, I will explain the reasoning for my research.

As stated above for the p-value, I was able to perform a hypothesis test for the regression coefficients of β₁, β₂, β₃. The coefficients of β₁, β₂, β₃ are the same as x₁, x₂, and x₃. This was examined by looking at the individual p-values to verify if these coefficients will be used in the model for explanation.

7. Compute multiple regression equation (vy is response, vthree, vtwo, and vvthree are explanatory variables):

– Predict the value of a dependent variable based on the value of at least one independent variable – Explain the impact of changes in an independent variable on the dependent variable
