Consider the following summary data on the modulus of elasticity (✕ 10⁶ psi) for lumber of three different grades.

Grade	J	x_i.	s_i
1	9	1.61	0.22
2	9	1.54	0.25
3	9	1.43	0.21

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 =

What can be said about the P-value for the test?

P-value > 0.100 0.050 < P-value < 0.100 0.010 < P-value < 0.050 0.001 < P-value < 0.010 P-value < 0.001

What can you conclude?

Reject H₀. At least two of the three grades appear to differ significantly. Reject H₀. The three grades do not appear to differ significantly. Fail to reject H₀. The three grades do not appear to differ significantly. Fail to reject H₀. At least two of the three grades appear to differ significantly.
