Question

Question;Shown below are rental and leasing revenue?gures for of?ce machinery and equipment in the UnitedStates over a seven-year period according to the U.S. Census Bureau. Use these data to run a linearregression and then forecast the rental and leasing revenue for the year 2012.Year Rental and Leasing (\$ millions)2004 5,8602005 6,6322006 7,1252007 6,0002008 4,3802009 3,3262010 2,642Suppose a researcher gathered survey data from 19 employees and asked the employees to ratetheir job satisfaction on a scale from 0 to 100 (with 100 being perfectly satis?ed). Suppose thefollowing data represent the results of this survey. Assume that relationship with supervisor is ratedon a scale from 0 to 50 (0 represents poor relationship and 50 represents an excellent relationship),overall quality of the work environment is rated on a scale from 0 to 100 (0 represents poor workenvironment and 100 rep resents an excellent work environment), and opportunities for advancementis rated on a scale from 0 to 50 (0 represents no opportunities and 50 represents excellentopportunities).Answer the following questions:A) What is the regression formula?B) How reliable do you think the estimates will be based on this formula? How can you tell?C) Are there any variables that do not appear to be good predictors of Job satisfaction? How can tell?D) If a new employee reports that her relationship with her supervisor is 40, finds the quality of thework environment to be scored at 75, works 60 hours per week and rates her opportunities foradvancement to be at 30, what would you expect her job satisfaction score to be?D) If a new employee reports that her relationship with her supervisor is 40, finds the quality of the work environment to be scored at 75, works 60 hours per week and rates her opportunities for advancement to be at 30, what would you expect her job satisfaction score to be?JOB SATISFACTION55208565457035609565851075805090754565RELATIONSHIP WITH SUPERVISOR2712403529422234503340537423147362032OVERALL QUALITY OF WORK ENVIRONMENT65137953436218758468721064824695824273TOTAL HOURS WORKED PER-WEEK50604565405075404560555045406055704055OPPORTUNITIES FOR ADVANCEMENT4228748324118324811332142464830392212Investment analysts generally believe the interest rate on bonds is inversely related to the primeinterest rate for loans, that is, bonds perform well when lending rates are down and perform poorlywhen interest rates are up. Can the bond rate be predicted by the prime interest rate?Use the following data to construct a scatter graph and then fit a regression line to the data.Report the regression formula and the r-squared value from the chart (rightclick on the line, select?Add Trendline? and select options to show these metrics).Bond Rate Prime Interest Rate5% 16%12 69 815 47 7
