Stat 431 Assignment 4 solutions 1. [16 marks] (a) [4 marks] We start with fitting the log-linear model without a three way interaction term. This model results in a deviance test D = 26.690, p − value = P(χ 2 8 > D) = 0. < 0.05 So we reject the H0: the model without the three way interaction fits as well as the saturated model (which is the model with three-way interaction). This implies that the three way interaction between age, breathlessness and coughing is necessary to d...

Nomenclature : Introduction The objective of this experiment is to measure the varying pressure across a converging-diverging channel and comparing the pressure with theoretical pressure from Bernoulli’s equation. Bernoulli’s principle states that as the velocity of the fluid increases, the pressure within the fluid decreases. In this lab, we will calculate the pressure based on the measured height of water in each taps for each flow rate. The flow rate measured by taking the time tak...

Siemens Electric Motor Works (A) Assignment Questions: 1. Calculate the cost of the five orders in Exhibit-4 under the traditional and new systems. Hint: first calculate the cost of processing an order and handling a special component. The cost of the five orders in Exhibit-4 under the traditional and new systems is shown below. This shows that the cost of each motor increases as the number of special components increases. To properly calculate of the five orders under the new system, we m...

HW 3 SOLUTION 1. An appliance manufacturer produces two models of microwave ovens: model H and model W. Both models require fabrication and assembly work; each H uses four hours of fabrication and two hours of assembly, and each W uses two hours of fabrication and six hours of assembly. There are 600 fabrication hours available this week and 480 hours of assembly. Each H contributes $40 to profits and each W contributes $30 to profits. a. Formulate this problem as a linear program. b. Us...

Problem Set 2 ECON 290, Models of Choice in Competitive Markets Jean Guillaume Forand∗ Fall 2016, Waterloo 1. Suppose that a firm has a the production function f(z1, z2) =    2z1 + z2 if z1 ≤ 2, 0 if z1 > 2. (a) Show that this production technology satisfies the no-free lunch property. Solution. Working with the production set, we need to show that (0, 0, q) ∈ Q only if q = 0. To see this, note that (0, 0, q) ∈ Q implies that q ≤ f(0, 0) = 0, so that because...

1. Which of the following best describes community-based nursing? a. A practice in which care is provided for individuals and families b. Providing care with a focus on the group’s needs c. Giving care with a focus on the aggregate’s needs d. A value system in which all clients receive optimal care ANS: By definition, community-based nursing is a setting-specific practice in which care is provided for “sick” individuals and families where they live, work, and attend school. The emphasis ...

CHM 101 Experiment 7 Dissolved Oxygen Levels in Natural Waters Objectives To learn the chemical reactions involved in fixing and analyzing water sample for dissolved oxygen using Winkler method. To determine the dissolved oxygen concentration of a natural water sample. Introduction The aesthetic appearance of bodies of water such as the color, surface growth and odor indicate an immediate perception of the quality of water. Other parameters give clear description of the quality of a w...
