What a finished BU 321 Unit 2 distribution problem set looks like
The finished set looks like a worked assignment rather than an essay, numbered to match the questions it answers. Each item opens by naming the distribution the situation calls for and the conditions that make it apply: fixed trials with two outcomes, counts in an interval, a continuous measure clustered around a center. Parameters come next, pulled from the scenario and labeled. The calculation follows, either written out or reported from the software function used, with the function and its arguments named so the result can be reproduced. A small sketch of the curve appears where it helps a reader see which region was computed. Each item closes on a sentence in business language, and the set states that the scenario was constructed for the assignment.
How a BU 321 Unit 2 example is structured
Naming the distribution before any figure is entered is the deliberate order, because a number produced by the right key on the wrong distribution is wrong in a way the arithmetic never reveals. Conditions are checked against the scenario in the same breath, so the fit is argued rather than assumed. Parameters are labeled before use, since a value read into the wrong slot is the commonest silent error in this unit. The calculation appears in whatever form the section accepts, but always in enough detail for a reader to repeat it. Sketches sit beside the region they describe rather than in an appendix. The plain sentence closes each item, because a probability with no business reading attached has stopped halfway, and this course grades the second half.
Distribution named before parameters
Each item states which model the situation calls for and why, since the arithmetic cannot reveal an error made at that choice.
Conditions checked against the scenario
The fit is argued from the situation itself rather than assumed, because most of the marks in this unit sit at the choice.
Parameters labeled before use
Values are named as they are pulled from the scenario, which is what prevents a figure entering the calculation in the wrong slot.
Working reproducible either way
Whether the set shows algebra or a software function with its arguments, a reader can repeat the result without guessing at anything.
Sketches next to their regions
A small curve appears beside the item it belongs to, showing which area was computed rather than leaving the region described.
Every item ends in business language
Each answer closes with a sentence a manager could act on, because a probability reported alone finishes only half the question.
Where marks go in BU 321 Unit 2
Problem sets bleed points at the distribution choice and at the last sentence. An item reaching for a normal calculation on a count of successes in a fixed number of trials produces a tidy figure that is simply the wrong quantity. Answers given as bare decimals, with nothing about what the number means for the scenario, leave the interpretation criterion empty. Parameters read into the wrong position, a mean where a rate belongs, go unnoticed by the writer and not by the marker. Rounding done early and carried through changes the answer and looks like miscalculation. Software output pasted whole, with no indication of which line answers the question, makes a marker hunt for it. Probabilities described as what will happen overstate what any model says.

BU 321 Unit 2 questions, answered
Do I have to show the formula if I used a spreadsheet?
Most sections want the function and its arguments recorded even where the algebra is not required, because that is what makes a result checkable. Write the function you called and what you passed to it, and say which cell or range held the data. If your instructions ask for hand working as well, show the substitution rather than only the final figure.
How much rounding is acceptable?
Carry full precision through the calculation and round once at the end, to whatever the instructions specify. Rounding an intermediate value and then continuing is the quiet source of answers that come close without being right, and a marker comparing against their own working will see the drift. State the rounding you used in a line.
When is the normal distribution the wrong choice?
Whenever the quantity is a count and the conditions of a counting model are met, among other cases your reading will list. The test is the situation rather than convenience: fixed trials with two outcomes, occurrences in an interval, and a continuous measurement all point toward different models. Name the conditions you checked before you calculated anything.
