2) Difference equations of the form xn+1=ƒ(xn) are a somewhat old-fashioned approach. A more modern approach is to use difference equations of the form Δx=ƒ(xn) where Δx = xn+1- xn. Explore the difference equation Δx=ƒ=r xn (1-xn). a) Algebraically determine the equilibrium and its stability as functions of r. b) Construct a simple bifurcation by hand by graphing the equilibria as a function of r. Represent a stable equilibrium with a solid graph and an unstable equilibrium with a dashed or...

1. Suppose the variable x is represented by a standard normal distribution. What is the probability of x < -0.6? Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12). 2. The mean is 55.3 and the standard deviation is 9.2 for a population. Using the Central Limit Theorem, what is the standard deviation of the distribution of sample means for samples of size 65?
