The research examining the effects of preschool childcare has found that children who spent time in day care perform better on math and language tests than children who stay home with their mothers. The results 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 standardized math test for which the population mean is μ = 81. The population distribution is normal. Use α = .01. a. Is this sample sufficient to conclude that the children with a history of preschool day care are significantly better from the general population? b. Compute the 95% confidence interval.
