In statistics we tend use the 'hat' notation to imply a statistic. We designate P to represent the proportion in the population. Because P is unknown and unknowable we use Phat to designate the proportion in the sample. Suppose 30 out of 100 people in my sample support Trump. P = unknown and unknowable.
The p-value (or probability value) is the probability of observing this outcome (RRRRRW) given the null hypothesis is true-it's the small probability referred to in (a), above. In this instance it's 0.016.
