A study published in Applied Psycholinguistics (June 1998) examined the language skills of low-income children. Each child in sample of 65 low-income children was administered the Communicative development Inventory (CDI) exam. One of the variables measured on each child was sentence complexity score. The sentence complexity scores had a mean of 7.62 and a standard deviation of 8.91. Construct and interpret a 95% confidence interval for the mean sentence complexity score of the population of all low-income children.
