1. Athabasca Fishing Lodge is located on Lake Athabasca in northern Canada. In one of its recent brochures, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 64 out of a random sample of 83 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the proportion of guests who catch pike over 20 pounds is different than 75%? Use a 5% significance level.

1. Consider the initial value problem $x' = \begin{bmatrix} 2 & -4 \ -1 & 2 \end{bmatrix} x, x(0) = \begin{bmatrix} 1 \ 2 \end{bmatrix}$. (a) Verify that $x_1(t) = \begin{bmatrix} 2 \ 1 \end{bmatrix}$ and $x_2(t) = \begin{bmatrix} 2e^{4t} \ -e^{4t} \end{bmatrix}$ are solutions of the system on R. (b) Show that $x_1(t)$ and $x_2(t)$ are linearly independent on R, and therefore, form a fundamental set of solutions of the system. (c) Solve the initial value problem on R.

INFOGRAPHIC 9.1 Theories of Motivation Motivational forces drive our behaviors, thoughts, and feelings. Psychologists have proposed different theories addressing the needs that create these drives within us. Let's look at the three most prominent theories of motivation. Some theories, like drive-reduction theory, best explain motivation related to physiological needs. Other theories focus on psychological needs, such as the need for an optimum level of stimulation as described in arousal theory. In his hierarchy of needs, Abraham Maslow combined various drives and proposed that we are motivated to meet some needs before others. Homeostasis motivates us to meet physiological needs. Humans have an innate need to seek an optimal level of stimulation. Boredom drives curiosity and activity-seeking behavior. It feels like anxiety to some, but sensation seekers are comfortable here. Drive-reducing behaviors restore balance. Equilibrium is created by deprivation. Arousal theory. Drive-reduction theory. Esteem. Hierarchy of needs. Love and belongingness. Physiological. Safety. Self-actualization. Self-transcendence. Abraham Maslow's theory combines physiological and psychological needs in a hierarchy, or sequence. We are motivated to meet higher-level needs when physiological needs at the base of the hierarchy have been met. Dedication to a cause, deep spiritual experiences, supporting others' goals. Self-fulfillment, being the best in one's field, expressing one's creativity. Financial independence. Family bonds, close friends, sense of community. Security, stability, shelter, protection. Food, water, sleep.

Pre-Lab Exercise 19-2 Autonomic Nervous System and the Cardiovascular System As you learned in Exercise 14-4 (pp. 381-382), the autonomic nervous system (ANS) has profound effects on other body systems and overall homeostasis. The cardiovascular system is no exception, which you will see in this unit's exercises. Fill in Table 19.1 with the basic effects of the two divisions of the ANS to refresh your memory. TABLE 19.1 Effects of the Divisions of the ANS SNS PNS Organ Sympathetic Nervous System Effects Parasympathetic Nervous System Effects Heart increase heart rate decreas heart rate Blood vessels serving skin and abdominal viscera Net effect on blood pressure Increase blood pressure decrease blood pressure Lungs (bronchial smooth muscle) bronchial muscle relaxation Bronchial muscle Contraction 19 Metabolic rate Urinary functions decrease urin produc Contract bladder Relax bladder Digestive functions decrease activity Increase activity

6.4.6 WP The stream function for a two-dimensional, nonviscous, incompressible flow field is given by the expression $\psi = -2(x - y)$ where the stream function has the units of ft²/s with x and y in feet. (a) Is the continuity equation satisfied? (b) Is the flow field irrotational? If, so, determine the corresponding velocity potential. (c) Determine the pressure gradient in the horizontal x direction at the point x = 2 ft, y = 2 ft.
