An experiment is conducted to determine whether intensive tutoring (covering a great deal of material in a fixed amount of time) is more effective than paced tutoring (covering less material in the same amount of time ). Two randomly chosen groups are tutored separately and then administrated proficiency test. Use a Significance level = 0.05

group 1 intensive n=12, x\bar = 46.31 , s=6.44

group 2 paced n=10, x\bar = 42.79, s=7.52
