Solution -
A student who was skeptical about this value decided to conduct a survey by randomly sampling 36 students. On average, the sampled students slept 6.6 hours per night.
The sample mean is the average of the 36 sampled students, which is 6.6 hours. So 6.6 represents the <u><em>sample mean.</em></u>
College newspaper stated that college students get an average of 7 hrs of sleep each night.
The claimed population mean is the stated average from the newspaper article, which is 7 hrs. So 7 represents the <u><em>claimed population mean.</em></u>
The correct answer is letter C.
The reason is because there are 12 cake donuts out of the 36 total. This is a simple ratio of 1 to 3. This means one out of every 3 people would get a cake donut. If there are 12 people, this is 4 groups of 3, so one person from each group of 3 is 4 people.
