USING JAVA, Class Design: Person The Person class is intended to be an abstract and simplified representation of a person. Each person will have an array of "friends" - which are other "Person" instances. Data to Store (2 Points) Name private instance variable with only private setter (2 Points) Friends private instance array with neither getter nor setter Actions Constructor o 1 Point) Take in as argument the name of the person (enforce invariants) o (1 Point) Initialize the array...
Exercise 5. (13pt) Consider a class of 16 students. Every week 4 students have to give presentation. At the end of the course, each pair of students has done exactly one presentation together (1) How many weeks does the course have? (Hint: use double counting) (4pt) (2) How can you interpret this as a block system? (4pt) (3) What is the total number of block in this system and what does it represent? Compare this to your answer in par...
2. I4] Prior to a test, 1/3 of a class of students study, and do so for n hours, where 0<ns 4 (n does not have to be an integer here). The other 2/3 of the class do not study at all. Those who study have a probability of ns of passing the test, and those who do not study have a 20% chance of passing. 117096 of all students that passed the test actually studied, what is a reasonable...
MATH1234 has an enrolment of 60 students. The lecturer, Brooke Malcolm, will randomly assign 20 students to each of three tutorials A, B and C Friends Xing, Yuxi and Ziyi want to know the probability that at least one of them will end up in tutorial A. The sample space for the 'experiment' of Brooke's choice is the set S of all possible class lists (unordered) for Tutorial A, and the event E of interest is that the outcome of...
2. In a large class, an in-person exam, where the lazy students couldn't do cheating, in a random sample of 8 lazy students, average exam score was 42.6 with sample standard deviation 4.4, while in a random sample of 10 non-lazy students, the average exam score was 49.8 with sample standard deviation 3.1. Assume that the two populations (Exam scores for the students who do not cheat) are normally distributed. Exam was out of 60points. (a) Assume that the two...
Exercise 1: Adding a Test Harness to the Person class To make it easier to test code that you have written for a Java class you can add to that class a main method that acts as a "test harness". A test harness is a main method that includes calls to methods that you wish to test. For convention this main method is the last method of the class. If you have a test harness, you do not need to...
Create a Student grading system. You should use a person base class (stores the name of the student). Derive a student class from the person class. The student class stores the student ID. The student class should also store the students 3 exams (Test 1, Test 2, and Test 3) and calculate a final grade (assume the 3 tests count equally). Create an array of students for a class size of 15 students. You can use the keyboard to read...
Can someone help me solving this? B6. A study is conducted in a class of 360 students investigating the problem of screen cracking in mobile phones. We assume that a) the number of screen cracking events follows a Poisson distributiorn and that b) the expected rate of screen cracking is 1 in 3 per phone per year. i) Write down the formula for the probability mass function of a Poisson random variable withh 3 marks parameter X, stating also the...
1. (5pts) Populate your "student" table with 20 or more students, such that: At least 4 of them (but not all!) have the last name "Jones" At least 3 students must have the first and last name 'Jessica Jones' At least 2 rows has a student with the GPA of 3.7 and 3.84, respectively At least 2 rows have a GPA of 2.7 and 3.69, respectively At least 2 rows have a GPA of 1.7 and 2.69, respectively At least...
1. (3) Determine the chromatic number of each of the two graphs below. Support your answer by showing a valid coloring, and showing that no fewer colors can be used. 2. (3) Sam has eight friends with whom he wants to have dinner before leaving town for the summer. He has limited time, so he'll try to dine with several at once. His goal is to see all of these friends in as few dinners as possible. Some of these...
