Solutions
Expert Solution
We have calculated mean and standard deviation using MS Excel. Following is the screenshot:
Answer a)
Sample mean years to maturity for corporate bonds = 9.7063
Sample standard deviation = 7.9805
Answer b)
CI = (7.1536, 12.2589)
95% confidence interval for the population mean years to maturity is 7.1536 yr to 12.2589 yr
Answer c)
Sample mean yield on corporate bonds = 3.8854
Sample standard deviation = 1.6194
Answer d)
CI = (3.3674, 4.4033)
95% confidence interval for the population mean yield on corporate bonds is 3.3674% to 4.4033%
