An experiment was carried out to compare flow rates for four different types of nozzle. (a) Sample sizes were 6, 7, 5, and 7, respectively, and calculations gave f = 4.22. State and test the relevant hypotheses using a = 0.01. O Ho M = M = 3 = 4 H at least two 's are unequal Ho: M1 M2 M3 M4 Ha all four 's are equal O Ho M1 M2 3 = 4 Hai all four 's are unequal O Ho: H1 H2 3 #14 H: at least two 's are equal 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 a. Fail to reject Ho because the P-value> a. Reject Ho because the P-value
