The heights, in inches, of the members of a barbershop quartet of singers are listed below. 72,68,67,73 If the population variance for this data set is 6.5, what is the standard deviation of the heights of the barbershop quartet? Round your answer to 2 decimal places. - Answer Correct answers:2.55 The standard deviation is the square root of the variance. Since the population variance is 6.5, the (population) standard deviation is 6.5−−−√≈2.549 . So to two decimal places, the ...

In a molecule or ion containing only covalent bonds, the formal charge of an atom is the hypothetical charge that the atom would have if electrons could be redistributed evenly between atoms. In neutral covalent molecules, formal charges are always a formality— each of the atoms contained therein are electrically neutral. Conversely, in covalently bonded ions (which carry an overall charge), the formal charge of a given atom may be the actual charge on the atom, but often is not. On the ...
