The measured weights of adult Australian females aged 18-24 have
an approximate normal distribution with mean 62.3kg and standard
deviation 12.3kg.
ii) What is the probability that a woman chosen at random from the
18 -24 population will be between 62.3 and and 67kg?
ii) What proportion of these women will be heavier than 70?
iii) What is the probability of finding a woman lighter than
55kg?
iv) Determine the weight which 90% of Australian women are
lighter than.
