Just exactly as you graph any other function: List a bunch of values for 'x', find the value of the function for each one, and start graphing the points, until you have enough points to see the shape of the function, and can draw more of it without more points. When you do that, you'll discover that -cos (x-pi) is equal to cos (x).

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the diameters of a population 1, and for this case we know the distribution for X is given by:

$X \sim N(3,0.1)$
