Answer: 27.4 hours

Step-by-step explanation:

According to the given statement "A survey of 45 teens found that they spent an average of 25.6 hours per week in front of a screen (television, computer, tablet, phone, etc.)."

Since the word average is synonym of word mean.

Therefore, the sample mean must have the nearest value to the given average.

From the given options 27.4 is the nearest value to the average of 258.6.

Hence, the population mean = 27.4 hours.
