Tourette€™s syndrome is an inheritable, childhood onset neurological disorder involving multiple motor tics and at least one vocal tic. A U.S. study that was published in the June 5, 2009, CDC Morbidity and Mortality Weekly Report indicated that the syndrome occurs in 3 out of every 1000 school-age children. Further analysis broke the data into ethnicity/race categories€”see the chart below. At the 0.05 level of significance, does this sample indicate that having Tourette€™s is independent of ethnicity and race?
