time flown are correlated so between these cost drivers‚ available ton miles seems to be the most reasonable cost driver since it indicate the time that the pilots and the flight attendant work for the Delta. Question 2 We first apply simple regression using each of the cost drivers mention above and other factor to estimate the salary by the cost drivers individually to see which one is best cost driver based on statistical reason and comparing R square. The scatter plots are shown in appendix

disprove these claims‚ as they reveal that other factors such as unemployment rates and population appear to contribute more to an increase in crime rates rather than the construction of Walmart stores. The software Minitab is used to analyze linear regression with the inputs population‚ demographics‚ high school graduation rates‚ unemployment rates‚ median household income‚ and the number of Walmart Supercenters and the output property crime rate. The overall purpose of the analysis was to reveal

number of Instagram followers ranged from 0-2122. By using MiniTab‚ we were able to analyze our data thoroughly and through a mathematical lense. For our R^2 value we got 19.2% (.192)‚ which would put our R value at -.443. As for our least-squares regression line‚ MiniTab outputted that the predicted number of Facebook Friends is equal to 588 plus 42.5 times the number of weekly visits to the Jig (Predicted # of Facebook Friends = 588 + 42.5(# of Jig weekly Visits)). We have attached our residual plot

DESIGNING A PAY PLAN STRUCTURE ESTABLISHING A COMPENSATION PHILOSOPHY The first step in designing a pay structure is to establish/identify an organization’s compensation philosophy. During this phase of the design‚ it is determined where within the market the organization wants to position itself‚ i.e.‚ at market‚ as a leader in the market or lagging the market. Once this decision has been made‚ range penetration strategies must be determined. This phase of the plan design deals with how an

obtain the residuals of the estimation and to formally test for heteroscedasticity in the model. In this lecture‚ we will focus on testing the model errors for serial correlation. Recall that‚ in order to make valid inferences using the linear regression estimates‚ we need the errors of the model (i.e. residuals) to satisfy the following key assumption: • The errors of the model are independent of each other (this is the assumption of non-serial correlation): [pic] for [pic].

the impact of three factors‚ namely Sales‚ Fixed assets and Interest paid on the profitability of a logistics company. Econometric tool of multiple linear regression model was used for analyzing the impact of above factors on profitability of a major logistics company GATI Limited. Based on the financial data of last 10 years 2000-2009 the regression analysis has revealed that profitability of GATI ltd. is significantly affected positively by increase in fixed assets and adversely affected by increase
