Consider the accompanying data on plant growth after the application of different types of growth harmane. 1: 13 15 6 14 2: 21 12 19 18 3: 19 14 21 16 4: 8 10 18 9 5: 7 10 15 7 A USE SALT (3) Perform an Ftest at level a - 0.05. State the appropriate hypotheses. H: at least two s are equal H: all five /'s are unequal O Ho: P - Pz - - P4- H: at least two H,s are unequal O Ho * ":* ":* "4* Fs H: all five u's are equal Calculate the test statistic. (Round your answer to two decimal places.) What can be sald about the Pvalue for the test? OPvalue > 0.100 O 0.050 < P-value < 0.100 O 0.010 < Pvalue < 0.050 O 0.001 < Pvalue < 0.010 O P-value < 0.001 State the concluslon in the problem contect. O Reject H.. There appears to be a difference in the average growth of at least two groups. O Fall to reject Hp. There appears to be a difference in the average growth of at least two groups. O Reject He. There does not appear to be a diference in the average growth. O Fall to reject H.. There does not appear to be a difference in the average growth. (D) What happens when Tukey's procedure is appled? (Round your answer to two decimal places.) Which means differ significantly from one another? (Select all that apply.) O, and 07, and 07, andi, O7, and . 07, and . 07, and O7, and. O7, and . O7, and . O There are no significant differences. Are Tukey's method and the Ftest in agreement? O Yes O No
