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.

ra1l [238]

Total number of times she flipped a coin =200.

Total number of heads in the experiment=92

Total number of tails in the experiment=108

Therefore probability of the coun landing heads up in this experiment is 0.5

In the above experiment, the probability of the coin landing heads up is

P(H)= 92/200 = 0.46

In the above experiment, the probability of the coin landing tails up is P(T) = 108/200 = 0.54

The ratio obj represent the experimental probability of the coin landing heads up in this experiment

Therefore the correct option is 1.
