E. Longitudinal study 12. A researcher is examining the effectiveness of a new drug on serum blood glucose in an anmal model of diabetes. He gives 20 rats a single dose every day for 1 week and gives a similarly matched group of 20 rats a daily placebo dose over the same 1-week period. Following the final dose administration, the investigator measures the blood glucose level in the rats, using a value of 120g/dL as a cutoff do define hyperglycemia. He obtains the following data (see chart). What tests would be most appropriate to determine wehther administration of the drug increased the incidence of hyperglycemia?
