A sample size of 80 will be most reliable, because there is a less likely chance for error.

Answer: 80

Step-by-step explanation:

The sample size is very important if we want to conduct a research of any interest. The larger the sample size it will make research results more accurate and reliable to the researcher.

Also to detect a statistical difference with a certain strategy require a larger sample size.

From the given options 80 is the maximum value , so it must be representing the largest sample size .

Therefore, the sample size of a population of 200 is most likely to give a reliable conclusion is 80.

Graph the relation. Is the relation a function? Why or why not? {(–5, 6), (–2, 3), (3, 2), (6, 4)} No; a domain value has two ra

Answer:

Yes; there is only one range value for each domain value

Step-by-step explanation:

A relation can be defined as a function f(x) if for each value of the domain of x, there exists a unique value of f(x).

For example

(2, 4)(3, 9)(-2, 4)(4, 16) Is a Function

(2, 4)(2,6)(3, 8)(3, -8) Is Not a Function

To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned.

For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function. The graph is shown in the attached image.

The correct option is: Yes; there is only one range value for each domain value
