Course Description: This course includes a discussion of probability rules, descriptive statistics, and inferential statistics concepts. Draws upon real world cases to demonstrate the application of probability and descriptive statistics for making statistical inference in business and economics.Course Objective: This course will enable students to:Understand the concepts of statistical summary measures, probability, random Variables and their distribution, estimation and hypothesis testing, correlation and regression analysis. 2. Understand the use of computers in statistical calculations Collect analyzes and interprets business and economic data relevant for managerial decision making. Apply standard statistical inference procedures, and draw conclusions from such analysis.Report statistical results clearly and concisely.

Your job is to help finish a report comparing states that require competency test for graduation from high school versus those that don’t. Given the data set pertaining to various characteristics of these states. Write and submit report no more than 10 pages in length for the questions listed below. Attach all tables and charts in an appendix. The data set is provides separately in an excel file. You can access the data file from the course web page in blackboard.Definition:SATAverage combined verbal/math scores of Scholastic Assessment Test during 1994-95 school years.EXPENDcurrent expenditure for public elementary and secondary education for the 1995-96 school years, in billions of dollars.TAKERSPercentage of 1995-95 school year graduates who took the SAT ENROLLTotal enrollment in public elementary and secondary school in the United States; fall 1995 figure in thousands of students.TEACHEERSTotal number of public elementary and secondary teachers in the United States; fall 1995 figures in thousands of full time equivalentRATIOStudent-to-teacher ratio in the United States, fall 1995.
