Answer: Population mean = [tex]\mu=5.5[/tex]
Sample mean = [tex]\overline{x}=6.25[/tex]
Step-by-step explanation:
We know that the population mean [tex]\mu[/tex] is the average of the entire population.
The sample mean [tex]\overline{x}[/tex] is the mean of the sample which is derived from the whole population randomly.
Given : A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night.
Thus , the population mean = 5.5 hrs
Also, On average, the sampled students slept 6.25 hours per night.
It implies , the sample mean = 6.25 hours
