Task instructions
Attached is a dataset representing daily transfer volumes from GBP to ZAR for the latter three quarters of 2023.

Please analyse it and answer the following questions. 

Answers can be presented and working done in any tool you wish, but please include your working for reference.

Please don't put a lot of effort into the presentation. We're not assessing presentation ability with this task, just your answers and reasoning. You can present in any format you like. Notebooks are fine, as are slide based files.

1 a) Describe the distribution that our daily transfer volumes follow.
1 b) What real world cause do you think is behind this shape of distribution?
1 c) What are some of the implications that this distribution would commonly have on analysis that you might do?

2 Have transfer volumes along this route changed significantly from quarter to quarter in 2023?. How would you determine that the observed differences from quarter to quarter are 'real' as opposed to being the result of background fluctuations?

3 Estimate the total transfer volume for October 2023 (bonus, include a measures of range & certainty).
