In various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (2,-mean) 23 +23+ *** +z, deviation= mean= n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation(double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input in color): Enter numbers ('quit' to end): 1.9 2.5 3.7 1 3 4 2 quit The mean is 3.11 The standard deviation is 1.55738

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average (using integer division) and max. A negative integer ends the input and is not included in the statistics. Ex: When the input is: 15 20 0 5 -1 the output is: 10 20 Assume that at least one non-negative integer is input.
IN PYTHON Write a python that calculates the position of a car moving in a 2D-plane given the list of movements that should be executed in order. The movements are right, left, up, or down, followed by the number of units that the car has to move. The number of units can be either integer values or floating values but must be positive. If the input is invalid, then the program should print that there is an error and prompt the user to enter the input again. Note: The starting position of the car is x=0.0, and y=0.0.
Write a program that prompts the user to enter two inputs: some text and a word. The program outputs the starting indices of all occurrences of the word in the text. If the word is not found, the program should output “not found”. Example1:Input1: my dog and myself are going to my friend Input2: myOutput: 0 11 31Example 2:Input1: Programming is funInput 2: myOutput: not found
Based on the case above, clearly define the following item : Data
Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices: 1. Sum of their square 2. Product of their square root 3. Square of their product The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping. Note: 1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit. 2. If the user chooses arithmetic operation No.2, format the output to three decimal places TEST CASES: If a user inputs a digit and choose arithmetic operation No.1: Input any number: 97834 Select an arithmetic operation…

Write a C program to assign passengers seat in an airplane. Assume a small airplane with seat numbering as follows. 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern with a ‘X’ marking the already assigned.For example: After seats 1A, 2B and 4C are taken the display should be 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D After displaying the seats available the program prompts…
In C program Given a set of numbers representing the customers visiting the store and a number n, print all the customer numbers that has visited the store n times. If there isn't any, print "No lucky customer" instead. Input The first number represents the count of customers visiting the store.The succeeding numbers are the customers of the store represented by numbers 0 to 99.The last number is the lucky number n. 56015115153Output The customers that have visited the store n times. If there's more than one customer, print them numerically in new lines. If there isn't any, print "No lucky customer". 15
Python Algorithms Part 1 – Binary SearchLet's play a little game to give you an idea of how different algorithms for the same problem can have wildly different efficiencies. If I choose an integer from 1 to 16 and ask you to guess what the number is, you can keep guessing numbers until you hit on it. When you guess wrong, I tell you whether you are too high or too low. Once you've guessed the number, think about the technique you used to decide each of your next guesses.If you guessed 1, then 2, then 3, then 4, and so on, until you guessed the right number, you used an approach called “linear search,” meaning you guessed the numbers serially and sequentially, as if they were lined up in a row. This is definitely one way to find the mystery number, but it could require as many as 16 guesses. However, you could get lucky, if the number was 1, you’d only need 1 guess. Using a linear search process, on average, you'd need 8 guesses.There is an approach that is more efficient than just…
