Formal Definitions of Big-Oh, Big-Theta and Big-Omega:
1. Use the formal definition of Big-Oh to prove that if f(n) is a decreasing function, then f(n) = 0(1). A decreasing function is one in which f(x1) f(r2) if and only if xi 5 r2. You may assume that f(n) is positive evervwhere Hint: drawing a picture might make the proof for this problem more obvious 2. Use the formal definition of Big-Oh to prove that if f(n) = 0(g(n)) and g(n)...

Searching/sorting tasks and efficiency analysis - Big-oh For each problem given below, do the following: 1. Create an algorithm in pseudocode to solve the problem. 2. Identify the factors that would influence the running time of your algorithm. For example, if your algorithm is to search an array the factor that influences the running time is the array size. Assign names (such as n) to each factor. 3. Count the operations performed by the algorithm. Express the count as a...

Match which type of test would be most appropriate for the given scenario. -A.B.C. You are investigating whether there was a change in performance between a group’s pretest and posttest. -A.B.C. You are investigating whether ABC Elementary School performed significantly higher than XYZ Elementary School on a standardized test. -A.B.C. You are investigating whether the mean IQ of all college students is lower than the national average of 115. A. Left (negative) tail B. Either (non-directional) tail C. Right (positive)...

Instructions In order to complete your case analysis successfully, you should consider identifying the role you are playing and the tasks you need to perform, analyzing the issues (qualitatively and quantitatively), providing a solution to the problem, and recommendation for each issue identified in the case. An average grade will come from you answering all questions with basic coverage and accuracy, showing all your work. Additional points come from including greater detail, astute and informed commentary where appropriate, and connections...

You are conducting a study among diabetic patients to see which type of exercise may benefit their blood glucose levels the most. You will split your patients in to 3 groups (cardio, cardio + weights, and control/no exercise) and after the intervention measure their blood glucose levels and compare the average glucose level between the 3 groups. Which statistical analysis is best suited for the scenario? Select one: Independent t-test Paired t-test One sample t-test ANOVA

1 Which statement describes best why you should document assumptions? a Assumptions might prove to be wrong. Knowing which assumptions were incorrect allows baseline adjustments in case of project crisis. b Assumption analysis is a valuable tool and technique to explore the validity of assumptions during risk identification. c Assumptions limit the project management team's options for decision making because they can not be controlled by the team. d In case of schedule or budget overruns, the documentation of assumptions...
