The correct option is (D).
Step-by-step explanation:
In statistics theory, population is a group of individuals from which a sample is collected to make inferences for this population. The sample collected is studied and various statistics are computed to estimate the population parameter value. For instance, mean, standard deviation, correlation.
In this case a sample of 10,900 Americans are selected and surveyed. The sample mean computed is used to estimate the population mean and the sample standard deviation is used to estimate the population standard deviation.
Thus, the population under study is all Americans who sleep through the night.
The correct option is (D).
