The Normal curve is the sampling distribution of x when the null hypothesis H₀ : ? = 0 is true.
The P-value for the first cola in Example 15.2 is the probability (taking the null hypothesis ? = 0 to be true) that x takes a value at least as large as 0.3.

What is the sampling distribution of x when = 0?
This distribution appears in Figure 15.2.

Normal distribution with mean 0 and standard deviation 1.

Do a Normal probability calculation to find the P-value, for the first cola.
