Solution Steps

Step 1: Understand the distribution of z

The distribution of z, also known as the standard normal distribution, always has a mean of 0 and a standard deviation of 1.

Step 2: Analyze the given graphs

Graph A has a mean around 1, so it's not a standard normal distribution. Graph B has a mean around 14.51. Graph C has a mean of 0 and appears to have a standard deviation of 1.

Final Answer

\\(\boxed{C}\\)
