Solution Steps

To determine the type of sampling used, we need to understand the method described. The researcher selects every 933rd social security number, which indicates a regular interval selection from a list. This is characteristic of systematic sampling, where elements are selected at regular intervals from an ordered list.

Step 1: Identify the Sampling Method

The researcher selects every \(933^{rd}\) social security number to survey the corresponding person. This method involves choosing elements at regular intervals from an ordered list.

Step 2: Classify the Sampling Type

This selection process is characteristic of systematic sampling, where a fixed interval is used to select samples from a population. In this case, the interval is \(933\).

Final Answer

The answer is systematic sampling, which can be boxed as follows: \\(\boxed{\text{Systematic sampling}}\\).

A function that satisfies Laplace's equation is called a harmonic function. (a) Is (f(x, y, z)=x^2+y^2-2 z^2) harmonic? What about (f(x, y, z)=x^2-y^2+z^2) ? (b) We may generalize Laplace's equation to functions of (n) variables as [ partial^2 f / partial x1^2 + partial^2 f / partial x2^2 + cdots + partial^2 f / partial xn^2 = 0 ] Give an example of a harmonic function of (n) variables, and verify that your example is correct.

Fill in the blanks to complete the passage about political systems. Government is the formal, organized agency that exercises power and control in modern society. Governments are vested with the power and authority to make laws and enforce them. Max Weber defined power as the ability to get others to do one's bidding. When sociologists talk about authority, they are referring to the legitimate, noncoercive exercise of power.
