2) the state of ohio department of education has a mandated ninth-grade proficiency test that covers writing, reading, mathematics, citizenship (social studies), and science. the excel file, ohio education performance, provides data on success rates (defined as the percent of students passing) in school districts in the greater cincinnati metropolitan area along with state averages. a. suggest the best regression model to predict math success as a function of success in the other subjects by examining correlation matrix; then run the regression tool for this set of variables. b. develop a multiple regression model to predict math success as a function of success in all other subjects using the systematic approach described in class (e. g. stepwise refinement). is multicollinearity a problem? c. compare the models in parts (a) and (b). are they the same? why or why not?

Forecasting as a first step in the team’s decision making, it wants to forecast quarterly demand for each of the two types of containers for years 6 to 8. based on historical trends, demand is expected to continue to grow until year 8, after which it is expected to plateau. julie must select the appropriate forecasting method and estimate the likely forecast error. which method should she choose? why? using the method selected, forecast demand for years 6 to 8.

The cutting department of cassel company has the following production and cost data for july. production costs 1. transferred out 12,300 units. beginning work in process $0 2. started 3,900 units that are 60% materials 62,856 complete as to conversion labor 12,622 costs and 100% complete as manufacturing overhead 23,100 to materials at july 31. materials are entered at the beginning of the process. conversion costs are incurred uniformly during the process. determine the equivalent units of production for (1) materials and (2) conversion costs. materials conversion costs total equivalent units of production link to text link to text compute unit costs. (round unit costs to 2 decimal places, e.g. 2.25.) materials $ conversion costs $ link to text link to text prepare a cost reconciliation schedule. (round unit costs to 2 decimal places, e.g. 2.25 and final answers to 0 decimal places, e.g. 1,225.) cost reconciliation costs accounted for transferred out $ work in process, july 31 materials $ conversion costs total costs $
