-Consult Table 11-2. Which means are significantly different from each other?

• A) The 8-year-old group is significantly different from the 10-year-old group and the 12-year-old group, and the 10- and 12-year old groups do not differ significantly from each other.
• B) The 12-year-old group and the 10-year-old group differ significantly from each other, and no other comparisons are significant.
• C) The 12-year-old group differs significantly from the 10-year-old group, the 12-year-old group differs significantly from the 8-year-old group, and no other comparisons are significant.
• D) All three groups are significantly different from each other.
