Hi im someone who is a strugglnig a little with the statistics part of his course! I have a couple of question and would be very grateful if someone could answer.

I struggle a bit with turning equation into practical usage so if i see the working needed I will probably clock onto the concept very fast.

'Information of a packet of seeds says the germination rate is 92%, what is the probability that 95% of seeds in the packet of 160 will germinate?'

'The weight of a pakcet of crisps is 10 ounces, the amount that the packaging machene puts in these bags is beleived to have a normal model10.2 and a standard deviation 0.12 ounces

a) what fraction of all bags sold are underweight

b) what is the probablity that of a multipack fo 3 none are underweight

c) what is the probability that the mean weight of the 3 bags is below the stated amount

d) whats the probability that the mean weight of a 24 bag box of crisps is below 10 ounces
