the exact probabilities of the binomial distribution Suppose it is known that 30 percent of the items in a large manufactured lot are of poor quality. Suppose also that a random sample of n items is to be taken from the lot, and let Qn denote the proportion of the items in the sample that are of poor quality. Find a value of n such that P(0.2 ≤ Qn ≤ 0.4) ≥ 0.75 by using the exact probabilities of the binomial distribution

You, as the chief financial officer (CFO), decided that any meaningful improvement must begin with an in-service handbook titled Strategic Financial Management Positioning Report, Part I – Challenges and Concerns to help staff understand some preliminary critical financial management principles and concepts and the nature of challenges facing hospitals that warrants strategic repositioning. The report should address the following: Current issues or challenges confronting hospitals today Role of financial management decision making in the health services sector and how this role has changed over the years How financial management decisions affect the planning and operations of healthcare delivery services Where vision and mission statements fall with regard to financial management Financial goals for a typical hospital that maximize shareholder wealth and retain the financial viability of the hospital and the considerations for composing these financial goals Identifying functional areas or responsibility centers in the hospital

Q3) The axisymmetric part shown in Figure 1 to be produced from course copper powder and is to have a tensile strength of 200 MPa. The solid- state sintering of the green compact resulted in a linear shrinkage is 0.03. If the part is to be compacted using a die and an upper punch, then find the following using data in Figure 2: (a) The compacting force (b) The initial volume of the powder needed. (c) Assume you are an engineer in a company and you are asked to reduce the shrinkage that takes place during sintering, what would you do at any stage during Powder Metallurgy process to achieve this objective? Figure 1: Figure 2: Density of copper- and iron-powder compacts as a function of compacting pressure. Density greatly influences the mechanical and physical properties of P/M parts. Source: After F.V. Lenel, (b) Effect of density on tensile strength, elongation, and electrical conductivity of copper powder. (IACS is International Annealed Copper Standard for electrical conductivity). Q4) In question 3, if the porosity was found to be 1% of the final volume, determine (a) Powder Packing factor (b) Packing factor after pressing (c) Packing factor after pressing and sintering Q5) In question 3, If the part is to be compacted using a die and an upper punch.

Lab 1B (Chapter 2) Possible points: 50 Due Date: 01/29/2018 (Monday) by 11:59 AM on the blackboard. Late submission date with a penalty: 01/31/2018 (Wednesday) by 11:59 PM on the blackboard. Problem Statement: Male and Female Percentage Write a program that asks the user for the number of males and the number of females registered in a class. The program should display the percentage of males and females in the class. Hint: Suppose there are 8 males and 12 females in a class. There are 20 students in the class. The percentage of males can be calculated as 8/20=0.4, or 40%. The percentage of females can be calculated as 12/20=0.6, or 60%. The files that you need to upload to the blackboard: 1. Algorithm 2. Flowchart 3. MaleFemalePercentage.py The assignment will not be accepted after late submission date. Avoid Cheating
