13) Please open the worksheet in the Homework 2 Workbook labeled Markets Version C. This version is for years 1986-2015. ***The workbook contains several versions, so make sure that you open the correct one! *** In this problem, we wish to analyze the following question: are returns on the stock market influenced by the current inflation rate? The data for your analysis is in columns A, B, and C. The worksheet is set up as a computational template, where green-shaded cells designate where calculations might be required. NOTE: for this problem, you might not need to perform all of the possible calculations. Step 1: decide which variable is the explanatory variable (x-variable) and which variable is the response variable (y-variable). (This step is a critical preliminary step.) Step 2: calculate the R (R-squared) statistic of the least-squares line. What does the R (R-squared) statistic about the least-squares model? (Read the alternatives carefully.)
