To draw a plausible conclusion about which age group spends the most time playing with toys, you would need to evaluate the scatterplot data points that represent the different age groups and their corresponding hours of play.
Based on typical trends, younger children (like those aged 4- to 6-years) often engage in more playtime with toys than older children or teenagers. Therefore, without seeing the actual scatterplot, it is reasonable to conclude that:
The age group that spends the most amount of time playing with toys is 4- to 6-year-olds.
This option aligns with common patterns in child development and play behavior.
