Carry out an analysis of variance F test at significance level 0.01. State the appropriate hypotheses.
: all four u's are unequal
*H = Ert = ?H = Tr:H O
O Ho: H1 = H2 = H3 = H4
H: at least two u's are unequal
O Ho: H1 * H2 # Hz # H4
H: all four u's are equal
O Ho: H1 # H2 # Mz # M4

Give the test statistic. (Round your answer to two decimal places.)
f =
What can be said about the P-value for the test?
O P-value > 0.100
O 0.050 < P-value < 0.100
0.010 < P-value < 0.050
O 0.001 < P-value < 0.010
P-value < 0.001
State the conclusion in the problem context.
O Fail to reject Ho. There is insufficient evidence to conclude that the total Fe differs for the four formations.
Reject H. There is sufficient evidence to conclude that the total Fe differs for at least two of the four formations.
Reject H,. There is insufficient evidence to conclude that the total Fe differs for the four formations.
Fail to reject Ho: There is sufficient evidence to conclude that the total Fe differs for at least two of the four formations.
