Hypotheses

H0 : The mixing technique has no affect the strength of concrete.

H1 : The mixing technique significantly affect the strength of concrete.

 

Using ANOVA hypothesis testing, the calculated value of  fo is 2.55, tested at  0.05, 7, 9 .

Do the mixing techniques affect the strength of concrete?

Since f < fo.05, 7, 9 , fail to reject Ho. There is sufficient evidence to show that the mixing technique
significantly affect the strength of concrete.
Since f > f0.05, 7, 9 , fail to reject Ho. There is sufficient evidence to show that the mixing technique has no
affect the strength of concrete.
Since f > fo.05, 7, 9 , reject Ho. There is sufficient evidence to show that the mixing technique significantly
affect the strength of concrete.
Since f < f0.05, 7, 9 , fail to reject Ho. There is sufficient evidence to show that the mixing technique has no
O affect the strength of concrete.
Since f < f0.05, 7, 9 , reject Ho. There is sufficient evidence to show that the mixing technique significantly
affect the strength of concrete.
