Refer to the Archives of Pediatrics and Adolescent Medicine (Dec. 2007) study of honey as a children's cough remedy, In addition to the two experimental groups of children with an upper respiratory tract infection-one which was given a dosage of dextromethorphan (DM) and the other a similar dose of honey-a third group of children received no dosage (control group). The cough symptoms improvement scores for the children are reproduced in the accompanying table and saved in the HONEYCOUGH file. Conduct a nonparametric test to compare the distributions of cough improvement scores for the three dosage groups. Use α = .01
