Answer:
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 22.455 - 10.167 = 12.288
The upper end of the interval is the mean added to M. So it is 22.455 + 10.167 = 32.622
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).

Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
<h3>
</h3>
To solve for y cross multiply
That's
3( x - 1) = 2y
2y = 3x - 3
Divide both sides by 2 to make y stand alone
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
The points lie on a line. Such a pattern is called a linear relationship because it represents a straight line relationship between the coordinates of the points. We can describe the relationship between x and y in words as follows: The y-coordinate is three times the x-coordinate.....hope this helps
