< 2 of 10 > This test: 10 point(s) possible This question: 1 point(s) possible Submit For the same sample statistics, which level of confidence would produce the widest confidence interval? Explain your reasoning. Choose the correct answer below. 90%, because as the level of confidence decreases, $z_c$ increases. 99%, because as the level of confidence increases, $z_c$ increases. 99%, because as the level of confidence increases, $z_c$ decreases. 90%, because as the level of confidence decreases, $z_c$ decreases.

1. Let $U$, $W$ be subspaces of a vector space $V$. Define a mapping $L: U \times W \to V$ by $L(u, w) = u - w$. Define a mapping $F: U \cap W \to U \times W$ by $F(u) = (u, u)$. (a) Show that $L$ and $F$ are linear. (b) Show that $ImL = U + W$, $KerL = ImF$, $KerF = \{0\}$. (c) Deduce that if $V$ is finite dimensional, then dim $U +$ dim $W = $ dim$(U + W) +$ dim$(U \cap W)$.

Consider having three variables named a, b, c with values 1, 10, 20, respectively. Store these variables into a row vector called vec. Set two boundaries: a lower limit, that is low = 5; an upper limit, that is up = 15; Write a code to investigate if each component of the vector vec is inside or outside the boundaries. Store the results in the vector variable out_vec with the following scheme: out_vec(i) = 1 inside the boundary; out_vec(i) = 0 outside the boundary; Use an if-else structure inside a for loop in your code.

Determine the magnitude of gain $K$ so that $M_r = 1.4$ ($M_r$ is the resonant peak magnitude). $M$-circle equation is as follows: $\left(X + \frac{M^2}{M^2 - 1}\right)^2 + Y^2 = \frac{M^2}{(M^2 - 1)^2}$
