Consumer Reports provided extensive testing and ratings for more than 100 HDTVs. An overall score, based primarily on picture quality, was developed for each model. In general, a higher overall score indicates better performance. The following (hypothetical) data show the price and overall score for the ten 42-inch plasma televisions (Consumer Report data slightly changed here): Brand Price (X) Score (Y) Dell 3800 50 Hisense 2800 45 Hitachi 2700 35 JVC 3000 40 LG 3500 45 Maxent 2000 28 Panasonic 4000 57 Phillips 3200 48 Proview 2000 22 Samsung 3000 30 Use the above data to develop and estimated regression equation. Compute Coefficient of Determination and correlation coefficient and show their relation. Interpret the explanatory power of the model. Estimate the overall score for a 42-inch plasma television with a price of $3600. Perform test of significance for slope coefficient.

write a java program that implements the splay tree data structure for the dictionary abstract data type.

Initially the program reads data from "in.dat", and establishes an ordinary binary search tree by inserting the data into the tree. The data file contains integers, one per line.

in.dat file contents:

3456
5678
1234
2369
7721
3354
1321
4946
3210
8765

Then the program starts an interactive mode. The commands are as follows.

S 1000 - splay the tree at 1000

F 2000 - search/find the node with key 2000

I 3000 - insert a node with key 3000

D 4000 - delete the node with key 4000

For each command,

1. Report appropriate message after the command is executed. Examples are:

Splay is done

Search is successful

Search is unsuccessful

The key is inserted into the tree

Duplicated keys

The key is deleted from the tree

The key is not in the tree

2. Display the new tree.

QUESTION 36

1. You would like to invest in one of the three available investment plans: money market, bonds, or stocks. The payoffs (profits) of each plan under two possible future economic conditions, PE (poor economy) and GE (good economy), are shown below. The probability of the occurrence of PE is 0.2.

   PE GE

   Money Market 1000 2000

   Bonds 3000 2500

   P(U/PE) = 0.6   P(F/PE) = 0.4

   P(U/GE) = 0.2   P(F/GE) = 0.8

   What is the posterior probability P(PE/F)?

   	a.	0.238
   	b.	0.047
   	c.	0.089
   	d.	0.111
   	e.	None of the above

QUESTION 38

   PE GE

   Money Market 1000 2000

   Bonds 3000 2500

Use the International Stock Market database from “Excel Databases.xls” on Blackboard. Use Excel to develop a multiple regression model to predict the DJIA by the Nasdaq, the S&P 500, the Nikkei, the Hang Seng, the FTSE 100, and the IPC. Performing a stepwise regression analysis at a 5% level of significance, which independent variable is the best single predictor of the DJIA? This is Step 1 of the stepwise regression.

The supervisor of data services at Reid Hospital is responsible for all databases that are maintained in the facility. It has been determined there are new organizational needs in the area of biosurveillance. The medical director requests that the supervisor of data services investigate developing a registry or database to track cases of potential bioterrorism, communicable disease outbreaks, and other unusual diseases or symptoms.

What resources should be available to the data services supervisor to help define the biosurveillance registry and how can existing registries be useful in determining data elements? What value would a biosurveillance registry provide? Explain your position.

Complete Critical Thinking Activity 2: Resolving Names of Internet Resources.

You have an Active Directory–integrated domain named. csmtech.local, with two DCs that are DNS servers. You also have an Internet presence with its own domain name, smpub.com, and a DNS server that's not part of an Active Directory domain. You want the DCs to be able to resolve the names of csmpub.com resources and to act as backup for the csmpub.com DNS database. What can you do to achieve these goals? Describe the steps you would take. Write a short report of your results

If I use Yahoo! Finance, will I be able to find out what they capital structures and levels of leverage for Uber and Lyft on there? If it is not through yahoo Finance would it be a formula used to find the capital structures and leverage for the companies, Uber and Lyft? What is the process of finding the capital structure for Lyft and Uber?

Original Question: Using the CapIQ database, review the capital structures and levels of leverage for both companies. Also, review income statements and balance sheets for the past three years to determine trends for both firms (common size financial statements will help you with this review).

can you give me a brief description of your experience related to each of these bullets?
