Week 2 Lab |Step 1: First Year Costs | | Question 1: What would the first-year costs be to AML if it purchased the 10 used 20-foot containers? How long would it take to recoup the investment‚ assuming that the mushroom traffic continued? Based on 120 container shipments per year with 10% loads return or 12 containers‚ this would generate revenues equal to the associated cost.

Statistics Homework – Week 2 Chapter 1: 1.1 - Three different types of drinks are sold at a fast food restaurant – soft drinks‚ fruit juices and coffee. A) Explain why the type of drinks sold is an example of a categorical variable Categorical variables take values that fall into one or more categories. As there are 3 different types of drinks‚ they would all fall into their own categories rather than numerical. B) Explain why the type of drinks sold is an example of a nominally scaled

STAT 151 Introduction to Applied Statistics I Byron Schmuland CAB 473 byrons@ualberta.ca Why bother with statistics? If your experiment needs statistics‚ you ought to have done a better experiment. Ernest Rutherford Uncertainty is everywhere! Many processes in nature (chemical‚ physical‚ economic‚ etc.) follow laws that are not exact‚ but are subject to a certain amount of chance variation. It is impossible to eliminate all sources of variation from an experiment‚ no matter

Week 2 Reflection Perception Keys Michelle L. Strain Walden University Abstract This paper discusses two perception keys and will answer questions about Delaroche’s Execution of Lady Grey and Claude Monet Impression Sunrise. Monet’s painting uses light to create the scene on his painting. Delaroche uses detail for his painting. “Delaroche’s reputation was built on doing what the photograph does best-reproducing exact detail and exact perspective.” Perception Key (p.353) 1. Delaroche’s

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the
