The standard deviation of the sample was 8100 psi Assume that the yield strengths are nomaly distrbuted Does the evidence suggest that the standard deviation of yield strength ex (a) Determine the null and alternative hypotheses. Ho 😐 â–¼| â–¼|7000 psi H. | â–¼| â–¼|7000 psi (b) Calculate the P-value. P-value (Round to three decimal places as needed ) (c) State the conclusion for the test Choose the correct answer below ceeds 7000 psi at the α-o 01 level of significance? Complete part (a) through (d) below O A. Reject Ho because the P-value is less than the α :0 01 level of signficance O B. Do not reject Ho because the P-value is less than the 0 01 level of significance â—‹ C.
