Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.

Estimate the following probabilities:
i) P {E > 29.5 x 10^6 psi}
ii) P {E > 30 x 10^6 psi}
iii) P{E > 28 x 10^6 psi}
