August 26‚ 2012 MATH 533 Course Project Part C Professor Khago Introduction: The following report displays regression and correlation analysis for AJ Davis Department Stores data on credit balance and size. We will use the data collected from 50 credit customers to complete the following analysis; * Generate a scatterplot for CREDIT BALANCE vs. SIZE‚ including the graph of the "best fit" line. Interpret. * Determine the equation of the "best fit" line‚ which describes the relationship

Question 1) The presented situation best represents consumer-consumer rivalry. An auction is a consumer-consumer rivalry in which each consumer places bids to obtain what they are bidding for. Although Levi Strauss & Co. is the producer of the 110-year-old pair of Levi’s jeans‚ the company is in the position of consumer in an auction where the company is competing with other consumers. Question 2) The present value of $150‚000 to be received at the end of five years is: PV = (150000/(1.09^1)) +

Problem N°1 1.Formulate the null and alternative hypotheses. Null Hypothesis: The average (mean) annual income was greater than or equal to $50‚000 H_0: μ≥50000 Alternate Hypothesis: The average (mean) annual income was less than $50‚000. H_a: μ 30 we will use the z-test. As Ha:μ0.40 the‚ test is a right tailed z-test. The critical value for significance level‚ α=0.05 for a right tailed z-test is given in the table as: 1.645. Decision Rule: Reject H_0‚if z>1.645 3. Calculate the test
