Recent research suggests that the amount of time that parents spend talking about numbers can have a big impact on the mathematical development of their children (Levine, Suriyakham, Rowe, Huttenlocher, and Gunderson, 2010). In the study, the researchers visited the children's homes between the ages of 14 and 30 months and recorded the amount of "number talk" they heard from the children's parents. The researchers then tested the children's knowledge of the meaning of numbers at 46 months. The following data are similar to the results obtained in the study.

Does it appear that there is a difference between the two groups?
Low no talk parent
High no. talk parent
The scores for both the groups are nearly the same.
O The scores for children from the high number-talk parents are noticeably higher.
The scores for children from the high number-talk parents are noticeably lower.
