Alena has a pair of dogs, and she noticed they usually breed more male puppies than females. To check that, she bred them again and obtained 15 puppies, and 13 of them were males.
Let's test the hypothesis that each puppy has an equal chance of 50% of being either male or female versus the
alternative that the chance of a male puppy is greater.
The table below sums up the results of 1000 simulations, each simulating 15 puppies with a 50% chance of
being male or female.
According to the simulations, what is the probability of having 13 male puppies or more out of 15?
