Answer:For this case we know that the proportion of baby boys born in the United States has historically been 0.44 and that represent the information from a

populationsince is calculated from all the possible members of the study population of interest and represent the characteristic for all of these memebers so then is thepopulation proportion.By the other hand we know that in a

Simple random samplingSRS of n=45 newborn babies and find that 50.8% are boys so then the proportion of boys for this random sample is 0.508 and that represent asample proportionsince is calculated from a subsample of the entire populationSo then the best choice for this case is:

d. 0.508: sample proportion, 0.44: population proportion
