Answer:
18%
Step-by-step explanation:
% increase = <u>new population - old </u><u>population</u> x <u>100</u>
old population. 1
% increase = <u>237180 - 201000</u> x <u>100</u>
201000. 1
% increase = <u>36180 x </u><u>100</u>
201000
% increase = <u>3618000</u>
201000
% increase = 18%

Answer:
2) Slope=10/3
Step-by-step explanation:
2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3
4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

Answer:
At least 1245 parts should be sampled.
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 the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How many parts should be sampled in order to estimate the population mean to within 0.1 millimeter (mm) with 95% confidence?
This is at least n parts, in which n is found when 
Rouding up
At least 1245 parts should be sampled.
