P: 300

If I hypothesize that 70% of all my future coin tosses will come up heads, and I sample 15 coin tosses and get 13 heads, what is the probability that my hypothesis is correct?

Obviously you underestimated, so you need to calculate whether the difference 13/15  0.7 is significantly different from zero.
See figure 1 of http://www.sportsmed.org/tabs/resear...ete%20Data.pdf
