A Lecturer wishes to create a program that lists his students sorted by the number of theory assignment marks they have completed. The listing should be greatest number of assignment first, sub-sorted by name in lexicographical order (A to Z). A class Student stores the name and marks of assignment completed for a student. [5 marks]
Note: Assume the variable name of collection is list.
i. Provide a definition of Student with an equals() method. The comparison is based on name of the student. [3 marks]
ii. Write java statement to declare a collection variable list of type Student [2 marks]
iii. Implements interface Comparator such that fulfil a natural ordering that matches the given requirement. Define method compareTo() such that it compares based on greatest number of assignment first, sub-sorted by name in lexicographical order (A to Z)). [5 marks]
iv. Provide definition of find(String) method which returns the index if given name exists in collection. [2 marks]
v. Provide a static method in application class to display all students by calling toString method. Assume the name of object of collection is list. [4 marks]

Suppose that you have an experiment wherein 5 individuals are each receiving training on 3 different tasks (A, B, and C). The values represent the number of minutes taken to complete the task. Suppose further that we are interested in determining whether there is a significant difference in the mean time taken to complete each of the tasks or not. State the name of the design of this experiment and all of the hypotheses that you would test. (Do NOT test.)
