For each problem test the significance the Spearman Rank Correlation Coefficient. Show your calculation of the test statistic rs. Please show work so i understand how to do it! Exercise 1. Defense and wins. The data in the table below shows the wining percentage and the yards per game allowed in the 2014-15 season for a random sampling of teams. At α = 0.05, can you support the claim that there is a correlation between the winning percentage and the yards allowed? Team Winning percentage Total yards Baltimore Ravens 0.625 336.9 Cleveland Browns 0.438 366.1 Denver Broncos 0.750 305.2 Jacksonville Jaguars 0.188 370.8 New England Patriots 0.750 344.1 Oakland Raiders 0.188 357.6 Pittsburgh Steelers 0.688 353.4

Do the following code by using python: ( Thank!)

You roll two six-sided dice, each with faces containing one, two, three, four, five and six spots, respectively. When the dice come to rest, the sum of the spots on the two upward faces is calculated.

• If the sum is 7 or 11 on the first roll, you win.

• If the sum is 2, 3 or 12 on the first roll (called “Mygame”), you lose (i.e., the “house” wins).

• If the sum is 4, 5, 6, 8, 9 or 10 on the first roll, that sum becomes your “point.”

To win, you must continue rolling the dice until you “make your point” (i.e., roll that same point value). You lose by rolling a 7 before making your point.

3. Open Roof or Closed Roof? In a recent World Series, the Houston Astros wanted to close the roof on their domed stadium so that fans could make noise and give the team an advantage at home. However, the Astros were ordered to keep the roof open unless weather conditions justified closing it. But does the closed roof really help the Astros? The table below shows the results from home games during the season leading up to the World Series. Use a 0.05 significance level to conduct a Chi-Square Test for Association. Is there sufficient evidence to show that there is a relationship between wins and the open/closed status of the roof?

Conclusion:

Assume that your company sells portable housing to both general contractors and the government. It sells jobs to contractors on a bid basis. A contractor asks for three bids from different manufacturers. The combination of low bid and high quality wins the job. However, jobs sold to the government are bid on a cost-plus basis. This means the price is determined by adding all costs plus a profit based on cost at a specified percent, such as 10%. You observe that the amount of overhead applied to government jobs is higher than that applied to contract jobs. These allocations concern you. Point: Students could compare responses and discuss differences in concerns with allocating overhead.

Required Write a half-page memo to your company’s chief financial officer outlining your concerns with overhead allocation.

Suppose four teams, numbered one through four, play a single-elimination tournament, consisting of three games. Two teams play each game and one of them wins; ties do not occur. The tournament bracket is as follows: teams one and another team play each other in the first game and the remaining two teams play each other in the second game; the winner of the first game plays the winner of the second game in the third game.

Define a set ΩΩ so the elements of ΩΩ correspond to the possible outcomes of the tournament. An element of ΩΩspecifies the entire sequence of outcomes of the games. How many outcomes are there for the combination of what bracket is used and the game outcomes? (Assume the order the two games are played in the first round does not matter. For example, they could be simultaneous.)
