Consider the set of even single-digit number {0,2,4,6,8}. Construct the sampling distribution of the sample means for the size of 3 and the standard error.
Oil flows through a standard 25 mm diameter orifice under 5.5 m head at a
measured rate of 3 L/s. The jet strikes a wall 1.5 m away and 0.12 m
vertically below the centreline of the contracted section of the jet. Determine
all the coefficients of the orifice.
In your respective groups find an example of a South African company’s code of ethics. Upload the document OR Copy the link and paste it into a word document with the heading “Code of Ethics”.
After finding an example of a South African Company’s code of ethics read through it and name and discuss the ethical theory that your group argues this company adheres to. Make a clear and convincing argument (not exceeding 250 words) as to why (after reading the code of ethics) you think this is the ethical theory that the company subscribes to
Two of the five (5) foreign automobiles from an overseas shipment have slight paint blemishes. If an agency receives three (3) of these automobiles at random, list the elements of the sample space 𝑆 using the letters B and N for “blemished” and “non-blemished”, respectively. For each sample point, assign a value 𝑥 of the random variable 𝑋 representing the number of automobiles purchased by the agency with paint blemishes. Hint: There are eight (8) elements in the sample space.
Assume the following:
• Brad and Jenny both produce food and dishes;
• Constant opportunity costs;
• Brad can produce 100 tonnes of food or 100 tonnes of dishes;
• Jenny can produce 400 tonnes of food or 200 tonnes of dishes;
• In autarky (i.e. self-sufficiency without trade) each person produces both goods and the optimal mix before the trade for Brad is (80) tonnes of food and (20) tonnes of dishes. For Jenny, the optimal mix before the trade is (300) tonnes of food and (50) tonnes of dishes.
a) What is the opportunity cost of 1 tonne of food for Brad? What is the opportunity cost of 1 tonne of dishes for Brad? What is the opportunity cost of 1 tonne of food for Jenny? What is the opportunity cost of 1 tonne of dishes for Jenny?
b) Which person has a comparative advantage in food and which person has a comparative advantage in dishes?
c) What are the minimum terms of trade that each person would be willing to accept in order to trade?

QUESTION 2 Taylor and Weber's scientific management system suggests that management should do all the thinking; they should set the goals, plan and supervise. It goes on to suggest that the workers should NOT think at all; they should just do the tasks required of them. Many theorists argued that the aim of Taylor and Weber, namely increased efficiency, would not be met if managers did not consider how their workers felt. Substantiate this statement with a practical example of a principal who imposes a certain decision on teachers and does not consider their feelings & paint a scenario that prove that teachers can never just teach without thinking about or carrying out other issues related to teaching and learning.
