an advertisement for sleeping pills claims to cause 50% longer lasting sleep. you decide to compare this new pill to your original sleeping pill.
subject (A) takes the origianl sleeping pill and subject (B) takes the new pill. subject A slept for 30 minutes while B slept for 45 minutes.

I tried to figure this out but I didn't know how to solve this. I thought you would subtract 30 from 45 which equals 15. and since 15 is fifty percent of 30, i thought that the data supported the claims but i wasn't for sure.

could someone better help me please

But most people measure the effectiveness of a sleeping pill in terms of hours, not minutes. If A sleeps 6 hours, then B would have to sleep 9 hours to prove the claim.
