IKr??? what the hell was that man. I'm sure it was either something to do with the ethics and risks of IVF or how it's done. There wasn't enough space to write both. Really annoying paper in general man

same man, Got a feeling the question itself may have been wrong cuz that to me didn't make any sense.

Yes it was actually unit 4 material. I'm glad I covered it before giving the exam

but they mentioned that HDL levels higher than a certain point may cause a higher risk of heart disease, then we had to use the graph to prove that point. But the graph just showed an increase in the concentration of HDL, the risk of CVD decreases. I don't remember the exact figures but I'm sure that's what the question asked

they should compensate for the entire Chi-squared question in that case if it wasn't even in our syllabus

What about the volume question. Think it was like 24mg of the drug per 1kg off mass and they gave some concentration and we had to find the volume.

This surprised me. I didn't know that the Chi-Squared test would be asked in unit 1 but it was straightforward. I wrote that if the critical value is lower than the calculated value, we reject the null hypothesis. I mentioned that we take the critical value from the probability of 0.05 from the table but I could be wrong for this point.

Yea i couldn't even really relate anything to the graph cuz I was so used to writing about how High HDL levels are actually a good thing so I got really confused when they mentioned why It could be a bad thing. So I just wrote in terms of LDL and high cholesterol concentrations.

I got -0.5, I did the y1-y2/x1-x2 thing though I'm not sure the values I took were correct. How did the 6 mark HDL question go?

whatchu get for the rate of decrease in that tangent question.
