A Researcher Interested in the Effects of Daycare on Development

A researcher interested in the effects of daycare on development discovers that the number of hours spent in group day care settings prior to entering school and academic performance in first grade have a correlation coefficient of 0.08. The conclusion we could draw from this finding is that:

A) children who spend a great deal of time in daycare before age 5 do worse in school than children who spend less time in daycare.
B) children who spend a great deal of time in daycare before age 5 tend to do better in school than those with less daycare experience.
C) daycare experience tends to give children a head start in managing the social demands of school.
D) there is no important relationship between time spent in day care as a young child and academic performance in first grade.
