havent gotten an answer for the last Q I asked yet, but I have another one.
Week 7 workshop sheet. Question 1.
Consider a population consisting of 0,4,12
x ...........0............4.............12
P(x)........0.3.......0.2............0.5
Random sample of n=2 measurements is selected from the population
b) Calculate the probability for each possible sample
To do this I'm pretty sure we just times the probabilities together, correct me if I'm wrong.
eg. P{0,0}=0.3*0.3=0.09
b) This is the one I'm not sure how to approach:
Calculate the mean for each possible sample.
Is it just mean{0,1}= (X1+X2)/N = 0+1/2 = 0.5?
Or is it something more complex as probabilities are involved
