- A farm produces potatoes. The potatoes are packed into sacks.
The weight of a sack of potatoes is modelled by a normal distribution with mean 25.6 kg and standard deviation 0.24 kg
- Find the probability that two randomly chosen sacks of potatoes differ in weight by more than 0.5 kg
(6)
Sacks of potatoes are randomly selected and packed onto pallets.
The weight of an empty pallet is modelled by a normal distribution with mean 20.0 kg and standard deviation 0.32 kg
Each full pallet of potatoes holds 30 sacks of potatoes. - Find the probability that the total weight of a randomly chosen full pallet of potatoes is greater than 785 kg
