1. Using the "Westwood Man-hours data.jmp" file perform a simple linear regression: a. Describe what you find out about the field relationships using Distributions under JMP's Analyze tab to just look at the data. Is there a relationship possibly? How strong? 5 b. Illustrate a simple linear regression using JMP's "Fit-Y-by-X" capability under the Analyze tab. From "Bivariate Fit", select "Fit Line". 5 c. Describe the results: i. Linear Fit - Describe the equation in words. Is there a meaningful intercept? ii. Summary of Fit - Explain the significance of Rsquare. iii. Lack of Fit - Using Prob>F and alpha draw conclusions on the null hypothesis "No lack of Fit" iv. Analysis of Variance - Using Prob>F and alpha draw conclusions on the null hypothesis "Model is not significant" v. Parameter Estimates - Explain the findings on the Intercept and slope estimates. 5 d. Residual Analysis from "Linear Fit": i. "Save residuals and return to data table. ii. Using Analyze>Distributions, plot the histogram of residuals. 1. Using the "Westwood Man-hours data.jmp" file perform a simple linear regression: a.
