A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode , in a module named stats.py. Also include a function named mean , which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main: lyst = [3, 1, 7, 1, 4, 10] An example of the program output is shown below: List: [3, 1, 7, 1, 4, 10] Mode: 1 Median: 3.5 Mean: 4.33333333333333

In this problem, you have available to you a working version of the function round_up described in part (a). It is located in a module named foo. Using the given round_up function, write a function round_up_all that takes a list of integers and MODIFIES the list so that each number is replaced by the result of calling round_up_ on that number. For example, if you run the code, 1st = [43, 137, 99, 501, 300, 275] round_up_all(1st) print(1st) the list would contain the values [100, 200, 100, 600, 300, 300] Do not re-implement the round_up function, just import the food module and use it. Here is the code for the round_up function that can be imported using foo: def round_up(num): if num % 100 == 0 : #if number is complete divisible return num #return orginal num else: return num + (100-(num % 100)) #else add 100-remainder to num, if __name__ == '__main__': print(round_up(234)) print(round_up(465)) print(round_up(400)) print(round_up(89))
A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers, as defined in Section 5.4. Define these functions in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions. Ask users to enter the list of numbers, and then choose which function to apply to those numbers. After the single number is returned from the correct function, display to the user the list of numbers, the function selected and the answer in a format that is easy to understand.
For this problem set, you will submit java file named Homework.java Return Growing NumList This function will be given a single number, it should return a list of strings of numbers. Each string in the list will only contain a single number repeated an arbitrary amount of times. The number each string will contain will be equal to the current string's index+1. The number in the string should be repeated the same number of times as the string's index+1. Each number in the string should be separated by a space. This list should stop when its size equals the max number specified. Signature: public static ArrayList<String> returnGrowingNumList(int max) Example: INPUT: 3OUTPUT: [1, 2 2, 3 3 3] INPUT: 6OUTPUT: [1, 2 2, 3 3 3, 4 4 4 4, 5 5 5 5 5, 6 6 6 6 6 6]

The English HOD asked you to write a small program to assist the English teachers toRAMDOMLY assign learners to do their oral examinations. Each teacher has adifferent number of learners in their class, so they will have to put in the number ofstudents on a form. The program should then randomly return a number (which areallocated to each learner on the teacher’s class list) AND check whether the newlyallocated number has not been used before. Your program therefor only has to returnthe following output:Slot 1 – Learner number 37Slot 2 – Learner number 23Slot 3 – Learner number 18Slot 4 - Learner number 7Slot 5 – Learner number 1 (etc.)You decided that this will be a fun project to give to your IT learners. a. Write a memo (which includes the whole program code)b. Indicate how you will assess and allocate marks to the learners.
Inside this module, import random and blackout_utils, and define the following global variable, which you should use whenever appropriate: OPERATIONS = ['^', 'x', '/', '+', '-']For full marks, all the following functions must be part of this module: calculate(tokens): Takes one list of tokens as input corresponding to a mathematical equation. The function will evaluate both sides of the equality and return a list of three tokens: the result of the left-hand side (integer), the equals sign (string), and the result of the right-hand side (integer). The equation may contain any of the operations in the OPERATIONS list, as well as opening and closing parentheses. Your function should evaluate both sides of the equation while respecting order of operations (that is, parentheses, followed by exponentiation, then multiplication and division, and then addition and subtraction). Equations may have multiple sets of parentheses and nested parentheses. The contents of the inner-most nested…
in phython language Create a module file named mystatistics.py. This module should define two functions: mean() and median(). Both functions takes a list as a parameter. mean() function calculates the average of all elements in the parameter list and returns it. median() function sorts the list first. If the number of elements in the list is odd, it returns the middle element. If it is even then it averages the two middle elements and then returns the value. Python has its own statistics library which has mean and median functions. Use them to test your functions and place a testing code in your module.
