PROBLEM 1 It is well known that adult male heights follow a normal (Gaussian) distribution. The same is true of adult female heights. For general Canadian population in the range from 18 to 79 years of age, male height follows N(175 cm;7.5 cm), while female height follows N(162 cm; 7.5 cm). Depending on your gender, determine the following: I am (select one): O FEMALE MALE A. Make a (rough) sketch of the distribution, label it indicating the mean and your...
