The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the average number of passing yards per attempt (Yards/Attempt) and the percentage of games won (WinPct) for a random sample of 10 NFL teams for the 2011 season.†

(c)

Develop the estimated regression equation that could be used to predict the percentage of games won given the average number of passing yards per attempt. (Round your numerical values to three decimal places.)

ŷ =

e)

For the 2011 season, suppose the average number of passing yards per attempt for a certain NFL team was 6.1. Use the estimated regression equation developed in part (c) to predict the percentage of games won by that NFL team. (Note: For the 2011 season, suppose this NFL team's record was 7 wins and 9 losses. Round your answer to the nearest integer.)

An 8% semiannual coupon bond matures in 6 years. The bond has a face value of $1,000 and a current yield of 8.4681%. What is the bond's price? Do not round intermediate calculations. Round your answer to the nearest cent. $ What is the bond's YTM? (Hint: Refer to Footnote 7 for the definition of the current yield and to Table 7.1.) Do not round intermediate calculations. Round your answers to two decimal places.

Find the linear regression line for the following table of values. You will need to use a calculator, spreadsheet, or statistical software.

Enter your answer in the form y=mx+b, with m and b both rounded to two decimal places.

An 8% semiannual coupon bond matures in 5 years. The bond has a face value of $1,000 and a current yield of 8.1503%. What is the bond's price? Do not round intermediate calculations. Round your answer to the nearest cent. $ What is the bond's YTM? (Hint: Refer to Footnote 7 for the definition of the current yield and to Table 7.1.) Do not round intermediate calculations. Round your answers to two decimal places. %

We have two $1,000 bonds in a portfolio.

• Bond 1 has a maturity of 10 years, coupon rate of 7%, semiannual interest
• Bond 2 has a maturity of 8 years and a coupon rate of 11%, semiannual interest
• Assume that bond yields of all maturities (ytm) are 6%

a. what are the prices(value) of the bonds

b. If bond yields drop to 5%, what will happen to the bond prices

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. Now you need to create a function to find the smallest positive number that is evenly divisible by two numbers you input into the function. (For example, your input is 6 and 9, you need to find the smallest number which can be divided by 6, 7, 8 and 9)
