When is the Poisson distribution model for a count appropriate - Answer>>> 1) The number of
successes that occur in two non-overlapping units of measure are independent
2) The probability that a success will occur in a unit of measure is the same for all units of equal
size and is proportional to the size of the unit
3) The probability that more than one event occurs in a unit of measure is negligible for very
small-sized units
how does the accuracy of the normal approximation for a binomial distribution change as the
sample size n increases - Answer>>> it improves
how do you get a sampling distribution of sample proportion for binomial distributions -
Answer>>> take large number of samples of fixed sample size n, and calculate the sample
proportion p(hat) for each sample. plot these p(hats)
What is Var (x+y) or Var (x-y) if x and y are independent events - Answer>>> Var x + Vary y
(addition rule for the variances of independent events)
When are two random variables said to be independent - Answer>>> When
P(X=x|Y=y)=P(X=x)
If X and Y have correlation p(rho)- population coefficient, then - Answer>>> Var (x+y) = Var x
+ Var y + 2p(Var x)(Var y)
Var (x-y) = Var x + Var y - 2p(Var x)(Var y)
