enzymes came 2 times in jan 2015 and june 2010 i think it would be either cell membrane or enzymes or maybe mineral deficiency as well i don't know. Also do you guys have any summarised notes to study from?
can someone explain the answer to c (ii) in question 2 in nov 2017?
not sure of it either but i think you should first draw a vertical line at age 22 and stop where it crosses the mean curve.
then draw a horizontal line (make sure it's very accurate ) along the length of the whole graph. the horizontal line will cross two points of the 1 and -1 standard deviation. then draw two vertical line down at the point where the horizontal line Crosses and obtain the age range.
I guess this is what i kinda understood. hope it helps.
•The SDS can be used to draw error bars where the SD value is subtracted and added to the mean value. To scale Y-axis, the lowest value is the lowest mean minus its SD and the highest value is the highest mean plus its SD.
