Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
The anoles that changed were the descendants of the anoles studied four years earlier by Losos.
<h3>What is natural selection?</h3>
Natural selection is a term that refers to the evolutionary process that is based on the principle that establishes the survival of the fittest or the preponderance of the law of the strongest in a natural environment without external intervention.
In natural selection, the least fit or weakest individuals perish and their traits are not transmitted to the following generations by not reproducing.
According to the above, it can be inferred that the traits of the weak or less fit organisms studied four years earlier were not transmitted to the following generations, so the organisms studied by Losos four years later are not the same, but the offspring of The originals.
