Hi all
Week 5 grades are up, my apologies they are late... I mixed up which week I was meant to do.
Grades given are out of 100. I graded with kindness, mercy and goodwill (i.e. in your favor) but please let me know if there are major issues or tallying problems.
Some feedback (relevant for the final exam):
*Double check your null and alt hypotheses, they are easy to mix up.
*Also take care in expressing >= vs > (or <= vs <) in your null and alt hypotheses
*Be careful with rounding in early stages of multi-step calculations, it can lead to significant errors in the final result
*Exclude missing values from proportion denominators
Thanks
Simon
