identify the expected value, variance and standard deviation of a continuous random variable and evaluate them using technology
4.2.4
examine the effects of linear changes of scale and origin on the mean and the standard deviation
3.3.14
identify contexts suitable for modelling by binomial random variables
3.3.15
determine and use the probabilities P(X=x)=columnvector(nx)p^x(1−p)^(n−x) associated with the binomial distribution with parameters n and p; note the mean np and variance np(1−p) of a binomial distribution
