This task involves writing a program that calculates the standard deviation of all numbers in a list. First, the number of the number in the list is entered, then each number is entered. The program should print the standard deviation of the numbers in the list. Note, the values entered into the program are part of a random sample, which may need to be taken into account when choosing a method to calculate the standard deviation.

statistics.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then print the mean, median, and standard deviation of the list. The mean is the average of the numbers. The median is the “middle” value if n is odd, or the average of the two “middle” values if n is even. The standard deviation is the average amount of variability For example: $ python3 statistics.py154102-12345mean: 7.75median: 7standard deviation: 5.909032633745278
When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. Write a program to adjust the values by subtracting the smallest value from all the values. Assume that the list will always contain different numbers. Ex. If the list of numbers is: 40 50 10 90 75 The adjusted list is: 30 40 0 80 65 The program first will ask the user to enter the number of integers to be adjusted. Then The following functions should be used: The function dataCollection should be called to make a dynamic array to hold the user entered integers. It prompts the user to enter the list of numbers. A pointer to the array should be returned. The function minVal receives an array and its size as arguments. It finds and returns the smallest number in the array. The function adjust receives an array, the array size, and an integer as arguments. It will create an array with the same size as the argument array, but subtract the last…
Using Python This assignment is about temperatures and requires the main function and a custom value-returning function. The value-returning function takes a list of random Fahrenheit temperatures as its only argument and returns a smaller list of temperatures that are below freezing. The main function needs these steps in this sequence: create an empty list that will the hold Fahrenheit temperatures. use a loop to add 25 random integer temperatures to the list. All temperatures should be between 5 and 75, inclusive. use another loop to display all 25 temperatures on one line separated by spaces. report the highest and lowest temperatures in the list. 32 might be in the list. Report the index of the first instance of 32 or report that it didn't make the list. using slice syntax: print the first 10 temperatures in the list. print the middle 5 temperatures in the list. print the final 10 temperatures in the list. execute the custom value-returning function with the complete list as…
Monthly Sales: Create a program that reads the total monthly sales for an entire year. The program outputs the average sales of the year, the names of the months above this average, and the names of the months below the average. Use a list to store the names of the months in a year, and use another list to store of the total sales for each of those months.

Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.
Python coding out put screen needed A pile of cards contains 5 red cards and 5 black cards. Write a program to simulate removing one card from the pile at a time at random until you remove at least two red cards and three black cards. Show the card that was picked and the contents of the pile of cards at each step. Report the number of total number of cards drawn. Use a list to represent the pile of cards. Sample Output 1: Chose: B Pile contains: ['R', 'R', 'R', 'R', 'R', 'B', 'B', 'B', 'B']Chose: B Pile contains: ['R', 'R', 'R', 'R', 'R', 'B', 'B', 'B']Chose: R Pile contains: ['R', 'R', 'R', 'R', 'B', 'B', 'B']Chose: R Pile contains: ['R', 'R', 'R', 'B', 'B', 'B]Chose: R Pile contains: ['R', 'R', 'B', 'B', 'B']Chose: B Pile contains: ['R', 'R', 'B', 'B']Removed 3 red and 3 black cards.Total number of cards drawn: 6 Sample Output 2: Chose: B Pile contains: ['R', 'R', 'R', 'R', 'R', 'B', 'B', 'B', 'B']Chose: R Pile contains: ['R', 'R', 'R', 'R', 'B', 'B', 'B', 'B']Chose: B Pile…
python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.
Python's range() function only includes the values up to the specified stop value. The range() method should be used in conjunction with a generator function that includes the stop value. By passing in the initialization arguments of "start," "stop," and "step," the function will generate the necessary list.
1. Write a game of rock paper scissors, one of the choices will be from the user and the other from the computer (use random) Print results for each game.Play the games in a row until you exit the game. Explain each step as comment.Game rules:Rock crushes scissors, you win.Paper covers rock, you win.Scissors cut paper, you win. 2. Write a program that sorts a list in ascending order. Don’t use sort method.Ask user number of list elements (at least 10 elements)Enter all elements from keyboard and printed.Sort your list. 3. Write a code for craps game. Craps is a dice game in which the players make wagers on the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots, respectively. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, you win and play is…
Design a program that generates a seven-digit lottery number. The program should generate seven random numbers, each in the range of 0 through 9, and assign each number to a list element. (Random numbers were discussed in Chapter 5.) Then write another loop that displays the contents of the list.
