Part 1b. Give one example of some practical case where we canuse Normal distribution (for instance, IQ scores follow a normaldistribution of probabilities with the mean IQ of 100 and astandard deviation around the mean of about 15 IQ points.) In yourexample,
a) cite the source that claims the variable to be normallydistributed (Hint: Look to the examples and exercises in thebook)
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 thevariable
e) provide an estimated range of values for the variable
