Mean/Expected number of events of interest: λ = 9.8
poisson probability distribution
| P(X=x) = e-λλx/x! |
a)
P ( X = 0) = e ^-10* 10 ^ 0/0! = 0.0001
b)
P(X≥1) = 1 - P(X=0) = 1-0.0001 = 0.9999
c)
P(X≤2) = P(X=0) + P(X=1) + P(X=2) = 0.0001+0.005+0.0027=0.0033

2. Consider the system of two identical plates at x = ±a each with charge density σ that we studied in class and is in the lecture notes. Starting with the Poisson Boltzmann equation dr2 kTe we obtained 1 (dV 2 (de) -4π1Ba(0) exp(-V)=c with c a constant. This can be written 2 dr kTe or kTe a) Take x2 = 0 and zi = a because you know the electric field --(kT/e)dV/dz at these two places. Show from this...

3. (a) Consider the population of all families with two teenagers and a maid. Let G denote a girl, B denote a boy and M denote a maid. Assume that a teenager is equally likely to be a girl or a boy. We are interested in the timing sequence of the teenagers and the maid (in the same family) going to bed on a Saturday night. Let BMB represents one teenage boy goes to bed first, the maid goes to...

The problem and the data: A pharmaceutical company has developed a new drug designed to reduce a smoker's reliance on tobacco. Since certain dosages of the drug may reduce one's pulse rate to dangerously low levels, the product-testing division of the pharmaceutical company wants to model the relationship between decrease in pulse rate, y (beats per minute), and dosage, (cubic centermeters). Different dosages of the drug were...
