USinflation.xlsx This file contains inflation and unemployment rate data for the United States. CPI denotes inflation in all items contained in the consumer price index; Core denotes inflation in a measure of core consumer prices that excludes energy and other volatile prices from the measurement; and PCE measures inflation in personal consumption expenditures. The unemployment rate is denoted by Unemployment. A regression of PCE inflation against a constant and the unemployment rate suggests that: O a) over 4% of the variation in the unemployment rate is explained by variation in PCE inflation. O b) we cannot reject the null hypothesis that the coefficient on the unemployment rate is equal to zero against the alternative hypothesis that it is not equal to zero, at the one percent level of significance 0 c) based on the slope coefficient t-test, unemployment rate has a linear association with PCE inflation Q d) only 1.34% of the variation in the PCE inflation rate is explained by variation in the unemployment rate. 0 e) unemployment rate has a positive linear association with PCE inflation
