STATISTICS

Answer the given problem. Analyze what tool should be used.

1. The data in the following table resulted from an experiment that utilized a completely randomized design.

Treatment 1	Treatment 2	Treatment 3
3.9	5.4	1.3
1.4	2.0	0.7
4.1	4.8	2.2
5.5	3.8
2.3	3.5

Test the null hypothesis that 1 = 2 = 3, where (i) represents the true mean for treatment I, against the alternative that at least two of the means differ. Use = 0.01.

Follow the steps in solving the problem, namely:

1. Hypothesis ex. H0: = 9.0 H1: 9.0 2. Level of significance ex. = 0.01 3. Test Statistic ex. z = x - 0 / / n 4. Critical Region ex. graph and /2 = +-0.025 5. Computation ex. compute using formula 6. Decision ex. accept H0 since the computed z-value falls in the region of acceptance. 7. Conclusion ex. there is no reason to believe the ...
