Values vs. variables A variable is any measured characteristic or attribute that differs for different subjects. Variables are things that we measure, control, or manipulate in research. Simply something that varies. The variable is the name of the scale along which the values lie. Given several values, what is the name of the variable along which the values lie? 1. 16 ounces, 32 ounces, 1 pound: 2. One month old, 2 years old, 10 years old, 20 years old 3....

9. In a population of 5000 subjects, 600 posses a certain characteristic. A sample of 120 subjects selected from this population contains 18 subjects who possess the same characteristic. What are the values of the population and sample proportions? 10. In a population of 9500 subjects, 75% have a certain characteristic. In a sample of 400 subjects selected from this population, 78% possess the same characteristic. How many subjects in the population and sample, respectively, possess this characteristic? 11. According...
Example 1: Define a function that takes an argument. Call the function. Identify what code is the argument and what code is the parameter. Example 2: Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identify which kind of argument is which. Example 3: Create a function with a local variable. Show what happens when you try to use that variable outside the function. Explain the results. Example 4:...

Assume that we have a finite population of 5 elements on which we measured a random variable X. Below are the observations of Xover the population: {0,1,2,3,4). Assume that we want to select a random sample of size 3 form this population. Let S be the sample variance. a. Find the distribution of S2 b. Calculate E(S) c. Calculate Var(s)
