Dataset: IBM HR Analytics Employee Attrition & Performance dataset (you can download the dataset from kaggle)

The Variable Attrition is what we plan to use as our dependent variable. The variable contains a Yes if they stay with IBM and ‘No’ if they do not. We need to create this into a binary dummy variable with 0 if they do not stay with IBM (Attrition = ‘No’) and 1 if they do stay with IBM (Attrition = ‘Yes’). This will also need to be done to the variable Gender and OverTime. Gender we can assign “Male” to zero and “Female” to one. For OverTime we will assign 0 for “No” and 1 for “Yes”.

Create Pivot tables instead of correlation matrixes for categorical variables and do the data analysis.

For data analysis:

• Describe the data using the techniques above (e.g. “We can see in this scatter plot that there is a positive correlation between the number of hours in which the patient exercised per week and his/her weight loss.”). About one page without the images.

• Based on these observations, draw some insights. (e.g. “We believe the patient is burning calories when exercising, thus contributing to the loss of weight”). About one page.

• State actionable experiments based upon your insights. (e.g. “We will use multiple regression that includes hours exercised as an explanatory variable to model weight loss. We expect…”)

Considering the following different search trees, binary search trees, AVL trees, red-black trees, and others. Compare their advantages and disadvantages, running times, etc

The primary role citric acid cycle is to collect high energy electrons from the oxidation of carbons in the form of NADH and FADH2. If the electron transport chain is inhibited, would you expect the citric acid cycle to be more active or less active? Explain your answer.

Higher Education is in crisis? How can we be positive leaders amidst the chaos we see at our institutions? Is it unrealistic or just challenging? Does it take a miracle or just a change in mindset?

USING JAVA, PLEASE MAKE THIS AS SIMPLE AS POSSIBLE, THIS IS AN INTRODUCTORY JAVA COURSE

1. Design and implement a class called PairOfDice.

The class should include:

a. A non-default constructor, i.e. with parameters

b. A setter method for each instance data

c. A getter method for each instance data

d. A method roll() that rolls both dice

e. A toString() method that returns a string containing the colors of both dice, eg "Colors of both dice: Red,Blue "

f. A method pairSum that returns the current sum of the two die values. (in PairOfDice.java)

2. Write an application TestPairDice that uses the PairOfDice class to create a pair of dice. The application prints to the screen the sum of their face values. The program then rolls the pair of dice and prints to the screen the new sum of their face and the colors of both dice. (TestPairOfDice.java)

SAMPLE OUTPUT: Sum of face values before roll: 7

Sum of face values after roll: 6

Color of both dice: Red,Blue

13. In your opinion, what are the three more important resources to manage in an organization? Explain in detail the logic of your answer.

14. Concepts such as ‘socio-technology,’ ‘technology-structure,’ ‘technology-system;’ what do they have in common? Provide examples

15. Provide an example of Competitive Advantage and of Comparative Advantage. Explain the difference between them.

Rachel purchased a car for $22,500 three years ago using a 4-year loan with an interest rate of 7.2 percent. She has decided that she would sell the car now, if she could get a price that would pay off the balance of her loan.

What is the minimum price Rachel would need to receive for her car? Calculate her monthly payments, then use those payments and the remaining time left to compute the present value (called balance) of the remaining loan. (Do not round intermediate calculations and round your final answer to 2 decimal places.)

Minimum price= _________________
