Question

Bloomberg Intelligence listed 50 companies to watch in 2018 (www.bloomberg.com/features/companies-to-watch-2018). Twelve of the companies are listed here with their total assets and 12-month sales. Let sales be the dependent variable and total assets the independent variable. a. Draw a scatter diagram. b. Compute the correlation coefficient. c. Determine the regression equation. d.For a company with $100 billion in assets, predict the 12-month sales. e. Refer to Exercise 17. The regression equation is ŷ = 1.85 + .08x, the sample size is 12, and the standard error of the slope is 0.03. Use the .05 significance level. Can we conclude that the slope of the regression line is different from zero?
