Problem 05 (E35.3) Two identical audio speakers connected to the same amplifier produce in-phase sound waves with a single frequency that can be varied between 300 and 600 Hz. The speed of sound is 340 m s. You find that where you are standing, you hear minimum-intensity sound. (a) Explain why you hear minimum-intensity sound. (b) If one of the speakers is moved 39.8 cm toward you, the sound you hear has maximum intensity. What is the frequency of the sound? (c) How much closer to you from the position in part (b) must the speaker be moved to the next position where you hear maximum intensity?

(c) The p-value for testing H0: $\mu_d \le 3$ versus Ha: $\mu_d > 3$ equals 0.1062. Use the p-value to test these hypotheses with $\alpha$ equal to .10, .05, .01, and .001. How much evidence is there that $\mu_d$ exceeds 3? What does this say about the size of the difference between $\mu_1$ and $\mu_2$? (Round your p-value answer to 4 decimal places.) Answer is complete but not entirely correct. 0.0967 Reject H0 at $\alpha$ equal to 0.10 and 0.05 some evidence that $\mu_1$ and $\mu_2$ differ by more than 3.

Problem P6.5. Consider the matrix $A = \begin{bmatrix} 2 & -1 \\ 1 & 3 \end{bmatrix}$. (a) Find an elementary matrix decomposition of A. Do this by hand and show how you get each elementary matrix. (b) Use your elementary matrix decomposition to describe in complete sentences, using geometric words, how A transforms the plane. (c) Use your decomposition to clearly sketch and label each step of how A transforms the plane. Do so by following the standard unit square. You may do this either carefully by hand or on GeoGebra. (d) Exploration. Is the elementary matrix decomposition you found unique? In other words, could you have found a different collection of elementary matrices whose product is A? Explain.
