Answer:
35
Step-by-step explanation:
The formula for solving the area of parrelelograms is B(base) times H(height).
the height here is 5 and the base is 7 so the area is 35.
99% confidence limits
for population proportion is:
CL = P +- Z * √(P*(1-P)/N))
Where:
P = sample proportion
Z = Z-score taken at 99%
confidence = 2.575
N = sample size
Calculating for the
values:<span>
P = 350/500 = 0.7
N = 500 </span>
Substituting know values
to the CL equation:
<span>CL = 0.7 +- 2.575* </span>√<span>(0.7*(1-0.7)/500))</span>
<span>CL = 0.647 , 0.753</span>
<span>
</span>
<span>Therefore confidence limits range from 0.647 to 0.753.</span>
