Answer:
a) 
b) The should sample at least 293 small claims.
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 , which means that the answer of question a is z = 1.645.
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.
(b) If the group wants their estimate to have a maximum error of $12, how many small claims should they sample?
They should sample at least n small claims, in which n is found when
. So
The should sample at least 293 small claims.
Answer:
$4 a week? darn that's a scam
Step-by-step explanation:
It should take her two and a half weeks to get $10.
To deliver what is being asked of the given above, solve first for the slope of the line. Given two points the slope is calculated by,
m = (y2 - y1) / (x2 -x1)
m = (14 - 5) / (-2 - 1) = -3
Use the point - slope to write the equation of the line,
y - y2 = m(x - x2)
y - 14 = -3(x - -2)
<em> y = -3x + 8</em>
Therefore, the answer is letter D.
Here are the answers
