Good question. I've made some minor changes to the advice.

Saved a checkpoint:
As I said in one of our meetings, my main goal in creating this question was to show students that two equal means don't mean two equal distributions and to play around with the fact that all measures of average can be misleading when interpreted incorrectly. I started another question as advised by Chris, Christian and Lauren about salaries (many poor people vs few very rich residents leads to false beliefs about average salary in the area) but I don't think I'll manage to get it done up to a point where someone else can finish it, so I think someone else just needs to start that question from the scratch. A histogram could be included in the Salaries question. I tried to play around with Geogebra so I could include graphs in my future questions, but I did not have time to finish this successfully, so someone else may need to do this to cover the GCSE statistics.

This is a very good question, there isn't really much i would change just a few minor things.
Advice
a) You don't need the "first" in the first sentence here as there is only one column for Sweet Heaven.
When you say "Similarly for Tasty Hell:" i think the colon should just be a comma but i'm not 100% sure.
b) You could maybe split up this paragraph by starting a new line after each sentence, but it's up to you.

Thank you Chris, I have used

Good question. Just a couple of things:
In the statement you say that the shops will be referred to as $s$ and $t$, but this notation is not used in the question itself, just the advice, so why not introduce this shorthand at the start of the advice instead.
In your advice, you have several calculations involving fractions inside the align environment. This is fine, however you will notice that they appear quite squashed with the default line spacing. You could add
[1pt](play around with the number) immediately after the line-break (the\\) to add additional line spacing, e.g.
\overline{s} &= \frac{\sum s}{n} \\[2pt]...

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.
Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
This is an extension type part. There is no expected answer, and it's assumed that the marking depends on interactions within the part's prompt.
You can test this part's marking algorithm by interacting with the rendering of the part's prompt below.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |
|---|---|---|---|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
