Question

We produce cast iron and claim that it has an average tensile strength of 210 MPa. An independent engineering company carries out the relevant hypothesis test which yields a p-value of 0.99. What is the conclusion?

Answer 1

It is given that the p-value of the hypothesis test is 0.99.

If the level of significance is = 0.05.

We know that, if p-value < . We reject the null hypothesis.

And, p-value > . We do not reject the null hypothesis.

Now, p-value = 0.99 > = 0.05. We do not reject the null hypothesis and conclude that it has an average tensile strength of 210 MPa.
