Question 12 1 pts What is the primary purpose of "blinding" in an experimental study? ("Blinding" means patients and/or investigators are not made aware of the patients' treatment group allocation) Prevent patient's or investigator's knowledge of their treatment group (e.g., novel medicine vs. comparison medicine) influencing the outcome assessment (i.e., observation bias) Prevent patients with less severe disease (i.e., likely to have better prognosis) tend to self-select certain treatment. Obtain treatment groups with comparable distribution of potential confounding or prognostic factors. No answer text provided.

Problem 5: Your goal is to design a power delivery system that delivers power to a 15 Ω load. The load will be at the end of a 5 km long transmission line with a resistance of 20 Ω/km. The voltage needed at the load is 120 $V_{rms}$. a) Find the voltage required at the source and the power efficiency of the system, $\eta = 100 \frac{P_{load}}{P_{source}}$, when no transformers are used in the circuit. (5 points) b) Assuming a single ideal transformer is utilized between the transmission line and the load, find the turns ratio, N, which would achieve a 98% power efficiency while keeping the voltage at the source as small as possible. The voltage at the load must still be 120 $V_{rms}$. (10 points)

An argument that is often made in order to undermine a particular position involves the suggestion that making exceptions to universal rules will ultimately lead to more frequent and more inappropriate exception-making. This is known as the slippery slope argument.

Let f, g : [a, b) → B be functions. Prove that if there is a number S > 0 so that f and g are equal on the subset {z ∈ [a, b) : |z - b| < S} of [a, b), then the left limit of f at b exists iff the left limit of g at b exists and in this case we have lim f(z) = lim g(z).

The function $f(x)$ is a polynomial and hence it is defined for all real numbers. Its second derivative is given by: $f''(x) = -5(x+3)(x-1)^2(x-2)$. Find the interval(s) over which the function $f(x)$ is concave up. $( -3, 1)$ and $(2, \infty)$ $( -\infty, -3)$ and $(1, \infty)$ $( -\infty, -3)$ and $(1, 2)$ $(-3, 2)$ $( -\infty, -3)$ and $(2, \infty)$ None of the above.
