a) cite the source that claims the variable to be normally distributed (Hint: Look to the examples and exercises in the book)

b) mention the randomly distributed variable

c) provide an estimated value for the mean of the variable

d) provide an estimated value for the standard deviation of the variable

e) provide an estimated range of values for the variable
