A consultant wants to ask workers at a factory about the workers job satisfaction. Which of the following best describe a system
alexandr1967 [171]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define systemmatic sampling

Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size

STEP 2: Determine the answer

The option that follows the systematic sample of workers is the last option because it follows a fixed, periodic interval of "every 4th worker until 80 workers are selected".

Hence, the answer is:

The consultant takes a list of the workers and selects every 4th worker until 80 workers are selected.

Explain how to estimate 586 - 321 two different ways
murzikaleks [220]
<span>To estimate 586 - 321, you can round the numbers up or down to the nearest five.
586 can either become 570, rounding up, or 585, rounding down, which is closer. 321 becomes 320. It's not close enough to 325, nor to 315, for either of those to be good choices. 570 - 320 = 250 and 585 - 320 = 265. The actual solution to the original problem is 265, so, the second estimate, because they both go down by 1, is the closest.</span>
