use C++ Project 6 1. Using vectors or arrays, write a function named word_rev() that reverse any given word. 2. Write a program that will: Ask the user to enter a word. Save the entry as word_entered. Call word_rev on the entry Display the reversed entry (word_entered) 3. Write a function named prime() that determine whether or not a given number n (greater than one) is prime. The algorithm: If n is even then n is not a prime number...

4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...

Python Problem:
Variance Explanation:
Problem 1: Computing variance For this problem, you will write a function variance that takes a list whose elements are numbers (floats or ints), and returns their variance, a single number. (If you don't remember how to compute variance, check the lecture notebook; it's one of the intermediate steps in computing standard deviation.) You should not use NumPy or any other Python libraries for this problem. For now, worry only about correctness, not efficiency. Passing an...

I really need help with this python programming assignment Program Requirements For part 2, i need the following functions • get floats(): It take a single integer argument and returns a list of floats. where it was something like this def get_floats(n): lst = [] for i in range(1,n+1): val = float(input('Enter float '+str(i)+': ')) lst.append(val) return lst • summer(): This non-void function takes a single list argument, and returns the sum of the list. However, it does not use...

1. Table of descriptive statistical measures (arithmetic mean, standard deviation, smallest value and largest value) for the variables in the model with a detailed discussion of the table2. The equation is in the community form of the model you reached, then display the results of the estimated equation from the Gretl program with errors. Standard normal as well again with proper standard errors.3. Discuss and explain the results of the estimated model and then the number of reasons why the...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...

Write solutions legibly, and show all work. Walk the reader through your thought process, using English words when necessary. 1. Recall question 2 of the previous homework – We draw 6 cards from a 52 card deck and let X = the number of heart cards drawn. You already found the pmf back then. You’re allowed to use it here without re-deriving it. a. What is the expected value of X? b. What is the variance of X? What is...
