Step-by-step explanation:
Answer:
<em>(9,-5)</em>
Step-by-step explanation:
When you go down, the number will decrease. The vertical position is the Y axis. -3-2=5.
When you go right, the number will increase. The horizontal position is the X axis. 5+4=9

A scatter diagram has points that show the relationship between two sets of data.
We have the following data,

where <em>x</em> is the average number of employees in a group health insurance plan and <em>y</em> is the average administrative cost as a percentage of claims.
To make a scatter diagram you must, draw a graph with the independent variable on the horizontal axis (<em>in this case x</em>) and the dependent variable on the vertical axis (<em>in this case y</em>). For each pair of data, put a dot or a symbol where the x-axis value intersects the y-axis value.
Linear regression is a way to describe a relationship between two variables through an equation of a straight line, called line of best fit, that most closely models this relationship.
To find the line of best fit for the points, follow these steps:
Step 1: Find
and
as it was done in the below table.
Step 2: Find the sum of every column:

Step 3: Use the following equations to find intercept a and slope b:

Step 4: Assemble the equation of a line

Answer: Population = Total students attend the school.
Parameter = Proportion of students named by president correctly.
Step-by-step explanation:
Population for a particular study is the largest possible group of individuals that are essential to be considered.
Parameter = measure of characteristic in a population.
By the above definition, we have
Population = Total students attend the school(1800).
Parameter = Proportion of students named by president correctly.
I got -17, so if you are answering in absolute values then C.17 is correct
