η₁: median of control
η₂: median of inbred
Difference: η₁ - η₂
Null hypothesis	H₀: η₁ - η₂ = 0
Alternative hypothesis	H₁: η₁ - η₂ ≠ 0

Calculated z= 1.59, P=0.1113 which is > 0.05 level of significance.

Ho is not rejected.

There is not sufficient evidence to conclude that the age at diagnosis are different for males and females .
