Etchegaray‚ Ph.D. Abstract After running the "Research Methods for Managerial Decisions" simulation Team B will further explore the multiple regression model and how it relates to Coffee Time predicting weekly revenue more accurately using normal values and lagged values. The difference between the two models will also be explained. This paper will also look at Coffee Time’s adverting spending to travel agents‚ as well as provide the key decision maker in the simulation with recommendations

6.1 Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1‚ as in Table E.2)‚ what is the probability that a. Z is less than 1.57? b. Z is greater than 1.84? c. Z is between 1.57 and 1.84? d. Z is less than 1.57 or greater than 1.84? 6.5 Given a normal distribution m = 100 and s = 10 what is the probability that a. X > 75? b. X < 70? c. X < 80 or X > 100? d. Between what two X values (symmetrically distributed around the mean)

sufficiently large sample size from a population with a finite level of variance‚ the mean of all samples from the same population will be approximately equal to the mean of the population. Furthermore‚ all of the samples will follow an approximate normal distribution pattern‚ with all variances being approximately equal to the variance of the population divided by each sample’s size. Using the central limit theorem allows you to find probabilities for each of these sample statistics without having

Doing Statistical Analysis Excel provides a large number of statistical functions. These and the tools in the Analysis ToolPak cover most types of statistical analysis that you would need to do in finance and include in your models. Many people look at functions as "black boxes." You input the arguments‚ and the functions provide the answers. In a way this view is true‚ but it is also dangerous - you may use a function or tool incorrectly or misinterpret the results. So take the time to know
