An experiment was designed to compare lengths of time that four different drugs provided pain relief following surgery. The results
(in hours) are shown the table below

DRUG
A B C D
12 16 8 14
14 16 10 14
11 14 10 12
12 14 10

is there enough evidence to reject the null hypothesis that there is no significant
in lengths of pain relief for the four drugs at
alpha= 0.05
