Question

The probability that a birth in the United States is male during 2018 is 0.511. Suppose a random number generator from 1 to 1,000 is used as a statistical model to create simulated results for births in the United States during 2018. Suppose the numbers 1 to 511 represent a male birth in the United States during 2018 and 512 to 1,000 represent a female birth in the United States during 2018.
Explain whether the following results are consistent with the model, and if not, explain the expected number of male births and the expected number of female births for 300
trials.

In 300 simulated trials, 171 of the births are female and 129 are male.
