* Solution with the parametric method: Z-test.You can use a Z-test if you can do the following two assumptions: the probability of common success is approximate 0.5, and the number of games is very high (under these assumption, a binomial distribution is approximate a gaussian di...

(females grow 2 to 4 times faster than males16), increasing the proportion of females in cultivated populations will be economically beneficial. To achieve this goal, understanding the sex-determination and differentiation mechanisms ofC. semilaevisis particularly important. The primary sex ofC. ...
