Consider the following statement by a project analyst: "i analyzed my project using scenarios for the base case, best case, and worst case. i computed break evens and conducted sensitivity and simulation analysis. i computed npv, irr, the profitability index, and payback. in the end, i have over a hundred different estimates and am more confused than ever. i would have been better off just sticking with my first estimate and going by my gut instinct." critique this statement.

It is important to conduct many different experiments and estimates in a project for having as much statistic data as possible, because it is necessary to show proof on whichever project you are into. In order to avoid confusion, it's also possible to organize data in Excel sheets/tables so it can be visually easier to interpretate. Gut instinct isn't enough to prove something wrong or right, and few data means higher probability of things going in ways other than the expected.

i believe the answer is c

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
