they get the achievement test for high school students.
The failing rate of Uraguchi is known to distribute in β distributuion with its mode
The failing rate of irregulars is in β distribution with ω = 0.25 and κ = 12.
They correspond to Uraguchi ~ beta(8.5,3.5) and Irreglar ~ beta(3.5,8.5),respectively.
At a DoTeihen medical school, 9 alimni had the test, and 9 failed and 0 passed.
Infer the proportion of Uraguchi in this DoTeihen.
The graph shows their distribution.
