Answer:
Option C. between 6 and 18 hours per week
Step-by-step explanation:
We are given that distribution of times is symmetric and mound shaped and this implies that data is normally distributed.
We also know that in the normal distribution the 95% of data lies within 2 standard deviations i.e. mean± 2*standard deviation.
So, 95% of the television viewing times falls in interval
mean± 2*standard deviation
12±2*3
12±6
[6,18]
Thus, [6,18] is an interval where you believe approximately 95% of the television viewing times fell in the distribution.
