History of preschool day care are significantly different

Reference no: EM13143437

Other research examining the effects of preschool childcare has found that children who spent time in day care, especially high-quality day care, perform better on math and language tests than children who stay home with their mothers (Broberg, Wessels, Lamb, & Hwang, 1997). Typical results, for example, show that a sample of n=25 children who attended day care before starting school had an average score of M=87 with SS=1536 on a standardized math test for which the population mean is µ=81. Is this sample sufficient to conclude that the children with a history of preschool day care are significantly different from the general population? Use a two-tailed test with α=.01.
