Consider the following summary data on the modulus of elasticity (x 105 psi) for lumber of three different grades. Grade J 17,; s,- 1 9 1.64 0.25 2 9 1.54 0.22 3 9 1.43 0.21 l0 USE SALT Use this data and a significance level of 0.01 to test the null hypothesis of no difference in mean modulus of elasticity for the three grades. Calculate the test statistic. (Round your answer to two decimal places.) f=x What can be said about the P-value for the test? (9 P-value > 0.100 O 0.050
