Without being able to see the actual scatterplot, I can’t determine the correct response based on the points plotted. However, a plausible conclusion based on typical trends in children's playtime could be that younger children (such as those in the 2- to 4-year-old or 4- to 6-year-old age groups) tend to spend more time playing with toys compared to older children (like those in the 14- to 16-year-old age group), who generally have other interests and activities.
If the trend in the scatterplot suggests that younger age groups have higher hours spent playing with toys, then the response stating the age group that spends the most amount of time is likely one of the younger groups (2- to 4-year-olds or 4- to 6-year-olds).
If you can provide insight into the scatterplot's pattern, I might be able to give a more precise answer!
