the month(s) in which he/she purchased the software. No Lag model: Let us look at first model. Here we try to predict number of service calls based on the number of packages sold in the respective month. The scatter plot and histogram (see the excel sheet) as follows shows the number of product sold against the number of service calls received [pic] [pic] From the above two figures it is difficult make any comment on the relationship between number of packages sold and SCALLs.

Inflation in the United States is at an all-time high. The recession of the U.S. economy only hinders people more with high gas prices. A one population test using the One Factor ANOVA test and a five-step hypothesis test can be used to determine if gas prices are equally high in many different states. The samples used to test the hypothesis come from data collected from 30 randomly selected gas stations in six different cities. The hypothesis test and some solutions to consider may have an effect

P3-42 Solution This problem illustrates the use of least squares method to derive a cost formula that can be used to predict cost of an activity for a month‚ a quarter and a year. In preparing cost formula using least squares method‚ intercept represents fixed cost and slope represents the variable cost rate. Important Formula: Cost formula = Fixed cost + Variable rate * Level of activity Part 1 Step 1 Prepare a cost formula using the least squares method. x = $3‚212 + $15.15 * Number of
