A manufacturer of a margarine spread containing phytosterols
claims that a person’s cholesterol can be lowered by 10% using this
product for 3 months. Does the use of this margarine (with 2g of
phytosterols to a 500g tub) for 3 months reduce the LDL-cholesterol
level in the blood of healthy adults?
a) Design an experiment to answer this question. Comment on
elements of control, randomisation and replication in your design.
Your answer should include a flow-chart schematic with full
annotations.
b) State what type of data summary statistics you would measure in
your planned study.
c) State what type of inferential analysis you would apply to make
a decision about the manufacturer’s claim. (No actual analysis is
done … no data given.)
