Answer: 3.712 hours or more
Step-by-step explanation:
Let X be the random variable that denotes the time required to complete a product.
X is normally distributed.

Let x be the times it takes to complete a random unit in order to be in the top 10% (right tail) of the time distribution.
Then, 
![P(z>\dfrac{x-3.2}{\sigma})=0.10\ \ \ [z=\dfrac{x-\mu}{\sigma}]](https://tex.z-dn.net/?f=P%28z%3E%5Cdfrac%7Bx-3.2%7D%7B%5Csigma%7D%29%3D0.10%5C%20%5C%20%5C%20%5Bz%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5D)
As,
[By z-table]
Then,

So, it will take 3.712 hours or more to complete a random unit in order to be in the top 10% (right tail) of the time distribution.
Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.
