It is not possible to do a Stern-Gerlach experiment on a free electron to measure its spin

magnetic dipole moment; it is only possible if the electron is in a neutral atom. Explain

why. (Hint: There is a superficial answer, which has a superficial rebuttal. A complete

answer involves the uncertainty principle.)

what would happen to the values you calculated for kc in the experiment if the beer's law constant (k) value you used was high (e.g.you used 6000 M^-1 when the actual constant had a value of 5000 M^-1) ? Explain your answer.

Consider a binomial experiment with 16 trials and probability 0.60 of success on a single trial.

(a) Use the binomial distribution to find the probability of exactly 10 successes.

(b) Use the normal distribution to approximate the probability of exactly 10 successes.

(c) Compare the results of parts (a) and (b).
