"On depressed woman would not eat and was in danger of dying of starvation, but she seemed to enjoy visitors and the TV set, radio, books and magazines, and flowers in her room. The therapists moved her into a room devoid of all these comforts, and put a light meal in front of her; if she ate anything at oil one of the comforts was temporarily restored. The therapists gradually withheld the rewards unless she ate more and more. Her eating improved, she gained weight and within two months she was released from the hospital. A follow-up eighteen months later found her leading a normal life.'' -from The Story of Psychology by Morton Hunt, 1993. What type of learning is being applied in the woman's treatment?

Determine whether each statement makes sense or does not make sense, and explain your reasoning. A conditional statement can sometimes be true if its

It is more likely that the amount of fishing is governed by the current number of fish present, so instead of a constant number of fish being caught, the rate is proportional to the current number of fish present, with proportionality constant k, as $P^{\prime}=0.4 P\left(1-\frac{P}{10000}\right)-k P .$ Solve this equation, assuming a value of k = 0.05 and an initial condition of 5000 fish.

Refer to a small consumer survey in which 10 people were asked to choose a cola among Coke, Pepsi, and RC. If each person chose a cola randomly, what is the probability that at least one person did not choose Coke?

Businesses often make use of conditioning techniques in their commercials. Think of specific examples of such advertising. Describe how the principles of conditioning are used in those advertisements.

This exercise describes an example of a nonmeasurable set in R. If x and y are real numbers in the interval [0, 11, we say that x and y are equivalent, written $x \sim y$ x - y is rational. The relation $\sim$ is an equivalence relation, and the interval [0, 11] can be expressed as a disjoint union of subsets (called equivalence classes) in each of which no two distinct points are equivalent. Choose a point from each equivalence class and let E be the set of points so chosen. We assume that E is measurable and obtain a contradiction. Let $A=\left\{r_{1}, r_{2}, \dots\right\}$ denote the set of rational numbers in [-1, 11 and let $A=\left\{r_{1}, r_{2}, \dots\right\}$. a) Prove that each $E_n$ is measurable and that $\mu\left(E_{n}\right)=\mu(E)$. b) Prove that $\left\{{E}_{1}, {E}_{2}, \ldots\right\}$ s a disjoint collection of sets whose union contains [0, 1] and is contained in [-1, 2]. c) Use parts (a) and (b) along with the countable additivity of Lebesgue measure to obtain a contradiction.
