Answer:
82.56 cm squared
Step-by-step explanation:
12.9-8.6
4.3
4.3*6.4
27.52- area of the triangle on the left of the figure.
Then figure out the rectangle that completes the figure.
8.6*6.4
55.04
Add the two values to complete the figure:
55.04+27.52
82.56 cm squared should be correct.

Answer:
A sample size of at least 737 specimens is required.
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 width M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So:
A sample size of at least 737 specimens is required.
