Olga 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 $4$ puppies, and *all* 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*.
**Assuming the hypothesis is correct, what is the probability of having $4$ male puppies out of $4$? Round your answer, if necessary, to the nearest tenth of a percent.**

Let's agree that if the observed outcome has a probability *less* than $1\%$ under the tested hypothesis, we will reject the hypothesis.
**What should we conclude regarding the hypothesis?**
