In 2006, a study enrolled children into either center-based daycare (population 1) or at-home daycare (population 2). You believe that center-based interaction should be different from at-home daycare for a child's development, and th claim that center-based daycare should have different test scores from at-home day-care. Assuming the population variances of the score are equal between the two types of daycare, you obtain the following Excel output: T-Test: Two-Sample Assuming Equal Variances Center-Based At-Home Mean 61 65 Variance 225 169 Observations 120 80 Pooled Variance Hypothesized Mean Difference 0 df 198 t Stat P(T
