A survey of patients with cleft palate was undertaken. As part of the study, ethnicity was asked. There were 153 patients that were white, non-Hispanic; 12 African-American; 78 Hispanic; and 9 Asian. If the population of people that the patients were drawn from were 50% white, non-Hispanic; 5% African-American; 40% Hispanic; and 5% Asian, does the distribution of patient ethnicities match the population proportions?
