Question:
Calculate the probability Pn that n spins are up out of a total of N for N and N and put your results in a table. Calculate the mean values of n and n using your tabulated values of PNn It is possible to do the calculation for general p and q but choose p q for simplicity. Although it is better to first do the calculation of PN n by hand, you can use Program Binomial.
b Use Program Binomial to plot Py n for larger values of N Assume that p q Deter mine the value of n corresponding to the maximum of the probability and visually estimate the width for each value of N What is your measure of the width? One measure is the value of n at which Pyn is equal to half its value at its maximum. What is the qualitative dependence of the width on N Also compare the relative heights of the maximum of Py for increasing values of N
c Program Binomial also plots Pn versus n Does the width of Py n appear to become larger or smaller as N is increased?
d Plot in Py n versus n for N Choose Log Axes under the views menu. Describe the qualitative dependence of in Py n on n Can in Pyn be fitted to a paraboln of the form AB where A and B are fit parameters
