(b) Suppose the concrete will be used for a particular application unless there is strong evidence that true average strength is less than 100 MPa. Should the concrete be used? Carry out a test of appropriate hypotheses. State the appropriate hypotheses. O Ho:µ > 100 Hiµ = 100 O Ho: H< 100 H:µ = 100 O Ho: µ = 100 Hai u > 100 Ο H, μ= 100 Hiµ< 100 O Ho: µ = 100 H:H # 100 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P- four decimal places.) t = |-1.34 P-value = |0.1802 What can you conclude? O There is strong evidence that the true average strength is less than 100 MPa. The concrete should not be used. O There is not strong evidence that the true average strength is less than 100 MPa. The concrete should be
