Problem 3:

Modify StudentLinkedList class by adding the following methods:

•  printStudentList: print by calling and printing “toString” of every object in the linkedList. Every student object to be printed in a separate line.

•  deleteStudentByID(long id): delete student object from the list whose ID is matching with the passed parameter.

•  sortListByID(): sort the linkedlist according to students IDs.

•  findMarksAverage(): find the average of all marks for all students in the list.

•  findMinMark(int markIndex): find the student with the minimum mark in a specific index:

Our class has 35 students in it. Ten students are nursing majors, 15 said ice cream was their favorite dessert and three students are nursing majors AND said ice cream was their favorite dessert. a. How many students are nursing majors, but have a favorite dessert that is NOT ice cream? (hint, the 10 nursing majors includes the three who love ice cream.) (1 point) b. Draw a Venn Diagram (or other suitable representation) of this situation and then answer the following questions. (2 points) c. How many students are neither nursing majors nor said ice cream was their favorite dessert? (1 point) d. If one student is selected at random, find the probability that the student… i.is a nursing major and said ice cream was the favorite dessert (1 point) iv. is a nursing major or said ice cream was the favorite dessert (1 point) v. isn’t a nursing major (1 point)

Create a program that implements a singly linked list of Students.

Each node must contain the following variables:

• Student_Name
• Student_ID

In main():

1. Create the following list using addHead(). The list must be in the order shown below.

2. Print the complete list using toString() method.
3. Create another list using AddTail(). The list must be in the order shown below.

1. Print the complete list using toString() method.
2. Delete head note from both list.
3. Print the both list using toString() method.

Given a connected graph G with n vertices. We say an edge of G is a bridge if the graph becomes a disconnected graph after removing the edge. Give an O(m + n) time algorithm that finds all the bridges. (Partial credits will be given for a polynomial time algorithm.) (Hint: Use DFS)

V. Economic Trends or forecast

In this section list the economic trends or business cycles that you feel are relevant to investing. Provide information from Livingstone Survey and The Conference Board's LEI and CEI that may be used to forecast the economy’s direction.

Read the following scenario and in the lawsuit of Stella v McDonalds, list up to three arguments in favor of Stella and up to three arguments in Favor of McDonalds.

“I’m Stella Liebeck. I was in the car with my grandson one day, and he drove up to a McDonalds drive-thru. He asked me if I wanted anything. Of course I did! It’s McDonalds! So, I got a cup of coffee. Hey, I was 79. I needed a little caffeine. They handed him his order (Big Mac, supersized, and my coffee). He pulled over to the side of the line so I could add some milk and sugar. I had the cup balanced on my knees and took the lid off, and hot coffee spilled all over me! I spent 8 days in the hospital having skin cut off my body and grafted onto my knees to replace the burned skin! It was awful! My cotton sweatpants absorbed the coffee, scalding my thighs, buttocks, and groin. I suffered third-degree burns on six percent of my skin and lesser burns over sixteen percent. I lost 20 pounds (nearly 20% of her body weight), I lost so much weight I only weighed 83 pounds and had to undergo two more years of medical treatment.”

Bats are nocturnal mammals, feeding on insects at night and sleeping during the day. Many species of bats use bridges as daytime sleeping places. Their choice of daytime position on the undersurface of a bridge appears to be non-random. One theory is that the bats choose locations that will keep them safer from predators. The beams that support a bridge create two kinds of spaces: wide (approximately 55 cm) and narrow (approximately 17 cm); biologists believe the narrow spaces provide more safety. Investigators studying the sleeping position choices of the Big-eared Bat (Corynorhinus rafinesquii) observed that 57 out of 102 of them were in narrow beam spaces. The narrow beam spaces accounted for approximately 46% of the available area under the bridges. The investigators want to see if this sample provides sufficient evidence that the bats prefer narrow over wide sleeping space. What is the P-value for this test?

Choose the study design that best fits the following description: The records of 8,047 white male smelter workers, believed to have been exposed to high quantities of arsenic, were gathered for those who began work between 1938 and 1963. Death certificates were examined to ascertain the cause of death for this group up until 2000. They were compared to death certificates from the workers in other occupations of the same race, gender and time period. Higher rates of mortality from respiratory cancer and heart disease were found among those who had worked at least 15 years as smelter workers compared to those in other occupations.
