For number 16-20: A research study was conducted toexamine the differences between older and younger adultson perceived life satisfaction. A pilot study was conducted.to examine this hypothesis. Group 1 with ten older adults(over the age of 70) and Group 2 with ten younger adults(between 20 and 30) were give a life satisfaction test.Scores on the measure range from 0 to 60 with high scoresindicative of high life satisfaction; low scores indicative oflow life satisfaction.

Problem 8. Consider a randomly growing population in which there are Zn individuals in the population at generation n for n = 0, 1, 2,.... Each individual in generation n gives birth to a random number of offspring: say the ith individual in the nth generation gives birth to X) individuals in generation n + 1, where {X(n) : i ≥ 1, n ≥ 0} are independent and identically distributed random variables, each with range {0, 1, 2,...}. Then we can define Zn recursively: Zn+1 = [x(n) + ... + X(n) 0 and we suppose the population starts with Zo the mean number of offspring per individual in the population is E(X(")) = µ. a) Compute E(Zn+1|Zn = k) for k ≥ 0. b) Compute E(Zn+1|Zn). c) Compute E(Zn). d) What can you say about P(Zn What does this mean for the population? e) What do you expect might happen when μ> 1? = if Zn = k for k ≥ 1 if Zn = 0, = 1, a single individual at generation 0.
