(12 points) In an survey research of public companies listed in NYSE, 250 companies were randomly selected companies, and information regarding their debt-to-assets ratio were collected. The mean debt-to-total-asset ratio for the sample is 0.5625. Hint1: debt + equity = total assets Hint2: Assume the population standard deviation (6) is known to be 0.5. Hint3: use z-test 3.1 (6 points). Do these data indicate that NYSE-listed companies use more debt than equity? (significant at the 1% level) 3.2 (3 points). Construct a 95% confidence interval for the population mean debt-to-total- assets ratio. 3. 3 (3 points).
