python help Q1: Over or Under Define a procedure over-or-under which takes in a number x and a number y and returns the following: -1 if x is less than y 0 if x is equal to y 1 if x is greater than y *Hint: You can use cond (define (over-or-under x y)  'YOUR-CODE-HERE   )   ;;; Tests (over-or-under 1 2) ; expect -1 (over-or-under 2 1) ; expect 1 (over-or-under 1 1) ; expect 0     Q2: Filter Write a procedure filter-lst, which takes a predicate f and a list lst, and returns a new list containing only elements of the list that satisfy the predicate. The output should contain the elements in the same order that they appeared in the original list. (define (filter-lst f lst)    'YOUR-CODE-HERE   )   ;;; Tests (define (even? x)   (= (modulo x 2) 0)) (filter-lst even? '(0 1 1 2 3 5 8)) ; expect (0 2 8)

Purpose: One of the most commonly made decisions is based on comparing the means of multiple conditions. Significance tests for comparing means are critical in the decision making process. In this assignment, you will practice how to use t tests and ANOVA tests to compare the means of multiple conditions under one independent variable in different experiment design (between-group and within-group) Tasks: Please write an R script that performs the following operations in the order listed. At the beginning of each task, write a comment marking the task number. Name the file as: lab6-<your last name>.R  ANOVA tests 8. Import the 'iris.csv' dataset. Browse and understand the data in each column 9. Compute descriptive statistics and create boxplot for sepal length and species. 10. Select the appropriate test to determine whether there is significant difference in sepal length between the three species. Follow the steps of ANOVA analysis. Make sure you check whether the assumptions are…

Module/Week 2 ASSIGNMENT (INPUT/OUTPUT)The number of permutations of a set of n items taken r at a time is given by the following formulan !⁄r !(n-r)!: where n! is the factorial of n, r! is the factorial of r, and (n-r)! is the factorial of the result of n-r. The factorial of a number n can be solved using the following formula: 〖n!=e〗^(-n) n^n√2πn. If there are 18 people in your class and you want to divide the class into programming teams of 3 members, you can compute the number of different teams that can be arranged using this formula (n !⁄r !(n-r)!). Write a C++ program that determines the number of potential team arrangements. You will need to use the double type for this computation. Use the Lab Template you set-up last week, proper formatting, and appropriate comments in your code. The output must be labeled clearly and formatted neatly. Submit C++ Programming Assignment 2 by 11:59 p.m. (ET) on Monday of Module/Week 2.

assign(self, assignment:Assignment) -> AssignmentResult: """ This function is to simulate the process of the student receiving an assignment, then working on the assignment, then submitting the assignment and finally receiving grade for the assignment. This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later. Then an Assignment Result object should be created with the student's ID, the assignment…
