Do you think it is important for archaeological sites to be protected from development once they are discovered? What are the pros and cons of each side of this issue? Once discovered, should artifacts be left as they are, or removed and displayed for others to learn about? What are the pros and cons of each option? How can cultural or societal influences affect the progression of scientific discovery? Do those influences normally have a positive or negative effect on science's ability to advance?

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
