The answer to this question would be: <span>The new survey’s margin of error will be between 50% and 100% the size of the original survey’s margin of error.
A bigger sample will result in a narrower margin of error which is a good thing because your data will become more accurate. But twice size will not improve the margin into the half. It definitely became lower than 100% though
</span>
13 should be b and
14 is a because geometric mean to have a common ratio
Z = (x - m)/s
z = (38-40)/8
z = -2/8
z = -1/4
z = -0.25
The z score is -0.25
Step-by-step explanation:
Tan30=4/adj
adj Tan 30= 4
adj=4/tan30
adj=6.93m
Area=L×b
4×6.93=27.72m
We know that
if <span>Allison can complete a sales route by herself in 6 hours
then
100% of the sales route---------------> 6 hours
x%--------------------------> 1 hour
x=100/6-----> x=16.67%/hour
Allison </span><span>working with an associate, she completes the route in 4 hours
</span>then
100%------------------> 4 hours
x%----------------> 1 hour
x=100/4-----> x=25%
An associate in 1 hour complete-------> 25%-16.67%----> 8.33%
then
an associate complete in 1 hour--------> 8.33%
x hour--------------------------> 100%
x=100/8.33-----> x=12 hours
the answer is
12 hours
