Ha: the solution of soil significantly differ than the percent of condition and strength of concrete 2) Ftest statistics value is F = 3.201 3) P value is P = 0.089 4) Conclusion ; The p value is 0.089 is greater than 0.05 that is do not reject null hypothesis. It is conclude that the solution of soil is not significantly differ than the percent of condition and strength of concrete.
