A fisherman is interested in whether the distribution of fish caught in Green Valley Lake is the same as the distribution of fish caught in Echo Lake. Of the 342 randomly selected fish caught in Green Valley Lake, 181 were rainbow trout, 79 were other trout, 42 were bass, and 40 were catfish. Of the 495 randomly selected fish caught in Echo Lake, 210 were rainbow trout, 109 were other trout, 84 were bass, and 92 were catfish. Conduct the appropriate hypothesis test using an $\alpha$ = 0.10 level of significance. a. What is the correct statistical test to use? \begin{itemize} \item Independence \item Goodness-of-Fit \item Homogeneity \item Paired t-test \end{itemize} b. What are the null and alternative hypotheses? $H_0:$ \begin{itemize} \item Fish breed and lake are independent. \item The distribution of fish is the same for Green Valley Lake and Echo Lake. \item The distribution of fish is not the same for Green Valley Lake and Echo Lake. \item Fish breed and lake are dependent. \end{itemize} $H_1:$ \begin{itemize} \item The distribution of fish is the same for Green Valley Lake and Echo Lake. \item The distribution of fish is not the same for Green Valley Lake and Echo Lake. \item Fish breed and lake are dependent. \item Fish breed and lake are independent. \end{itemize} c. The test-statistic for this data = ______(Please show your answer to three decimal places.) d. The p-value for this sample = ______(Please show your answer to four decimal places.) e. The p-value is Select an answer $\alpha$ f. Based on this, we should \begin{itemize} \item fail to reject the null \item accept the null \item reject the null \end{itemize}

( 5 points) Consider the real 2 imes 2 matrices A=[[1,2],[0,0]],B=[[1,3],[0,0]],C=[[-1,-2],[0,0]]. Find the correct statement below: (A) A and B are not row equivalent, and they are not similar. (B) A and C are row equivalent, and they are similar. (C) A and B are similar since they are similar to the same diagonal matrix D=[[1,0],[0,0]]. (D) A and B are similar, but A^(5) and B^(5) are not similar. (E) No pair of the matrices are similar.

11. A flat, circular coil has 40 turns of radius 30 cm. At time $t = 0$, an external, uniform magnetic field perpendicular to the coil plane has a magnitude of 0.25 T and is decreasing linearly with time. At time $t = 0$, the induced emf is $9\pi$ mV. How long does it take for the magnetic to reach zero? (8%)
