Test the claim that the two beans have different mean times


This is a question from my professors exam review

Two competing headache remedies claim to give fast acting relief. An experiment to compare the mean times required for bodily absorption to a specific level gave results(times in minutes,assume normal)

brand 1: n=14 mean=21.5 s=8.1

brand 2: n=10 mean=17.8 and s= 7.0

Test the claim that the two beans have different mean times to absorption assume equal std deviations
