Distress in EMSworkers. The Journal consulting and Clinical Psychology reported on a study of emergency service (EMS) rescue workers who responded to the I-880 freeway collapse during a San Francisco earthquake. The goal of the study was to identify the predictors of symptomatic distress in the EMS workers. One of the distress variables studied was the Global Symptom Index (GSI). Several models for GSI, y, were considered based on the following independent variables: x1 = Critical Incident Exposure scale (CIE) x2 = Hogan Personality Inventory—Adjustment scale (HPI-A) x3 = Years of experience (EXP) x4 = Locus of Control scale (LOC) x5 = Social Support scale (SS) x6 = Dissociative Experiences scale (DES) x7 = Peritraumatic Dissociation Experiences Questionnaire, self-report (PDEQ-SR) (a) Write a first-order model for E(y) as a function of the first five independent variables, x1 –x5. (b) The model of part a, fitted to data collected for n = 147 EMS workers, yielded the following results:…

Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Assuming a linear relationship, use the least- squares method to compute the regression coefficients b0 and b1. State the regression equation that predicts the height of a tree based on the tree’s diameter at breast height of a person. Interpret the meaning of the slope in this equation. Predict the mean height for a tree that has a breast height diameter of 25 inches.

4. PC World rated four component characteristics for 10 ultraportable laptop computers: features; performance; design; and price. Each characteristic was rated using a 0-100 point scale. An overall rating, referred to as the PCW World Rating, was then developed for each laptop. The following tables show regression output examing relationships between the performance rating, features rating, and the PCW World Rating for the 10 laptop computers (PC World website, February 5, 2009).
