Population Dynamics Case Study

Graph: Take a graph sheet and divide it into 4 equal parts. Mark origin at the center of the graph sheet. Now mark +ve X-axis as Vf, -ve X-axis as Vr, +ve Y-axis as Ifand –ve Y-axis as Ir. Mark the readings tabulated for Si forward biased condition in first Quadrant and Si reverse biased condition in third Quadrant.

Problem 2: For two independent flips of a fair coin, let X equal the total number of heads in the two flips, and let Y equal the number of tails on the second flip. Find the joint PMF PxY(r, y).

F2 * Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. An article in the ASCE Journal of Energy Engineering ("Overview of Reservoir Release Improvements at 20 TVA Dams," Vol. 125, April 1999, pp. 1-17) presents data on dissolved oxygen concentration from streams below 20 dams in the Tennessee Valley Authority system. The sample mean from the observations is X 3.272 and the sample standard deviation is s = 2.130. Assume population is approximately normally distributed. Round your answers to 2 decimal places. = (a) Calculate the 95% two-sided confidence interval on the mean oxygen concentration. 2.29 i -1.2736 SUS 4.28 (b) Calculate the 95% two-sided prediction interval on the dissolved oxygen concentration for the next stream that will be tested.

A random experiment consists of drawing a ball from a box that contains 4 red balls (numbered 1,2,3,4) and 3 black balls numbered (1,2,3). State what outcomes are contained in the following events: a. E₁ = The event that the only balls with an even number are selected b. E2 = The event that only red balls with a number greater than 1 are selected c. E3 The event that only balls with a number less than 3 are selected For reference, an example of a response for such questions is as follows: = Q: E6 The event that only balls with an odd number are selected A: E6 = {R1, R3, B1, B3}. Here R₁ = event that Red ball with number 1 is selected, B3 = Black ball with number 3 is selected.. and so on..

(A) Suopces the current measurements in a strip of wire are normally distributed with ca-10(mA) and a varieocom (mA)² 1- What is the probability that a current measurement lies between 7.4 and 11.6 mA? 2-Drew the probability density function of the current distribution. (8) A factory produces light bulbs with a koown probability of P(D)-0.08 that & bulo is dalective. If a bulb is defective, the probability that the quality control test detects it is defective is P(TID)-0.90. Conversely, if a bulb is not defective, the probability that the test Telesly indicaton k as defective is P(TID)-0.05. calculate the probability that a light b is notually defective given that the test result is positive, F(DIT).

With the use of a table, with no more than 5 points, make a comparison between the characteristics of a carbon composite flywheel and a Lithium-ion battery.

The reading on a voltage meter connected to a test circuit is uniformly distributed over the interval (θ, θ + 1), where θ is the true but unknown voltage of the circuit. Suppose that Y1,Y2,...,Yn denote a random sample of such readings. a  Show that Y is a biased estimator of θ and compute the bias. b  Find a function of Y that is an unbiased estimator of θ. c  Find MSE(Y ) when Y is used as an estimator of θ .

I never could figure this first part out.
