Question

16.21 The given data on phosphorus concentration in topsoil for four different soil treatments appeared in the article "Fertilisers for Lotus and Clover Establishments on a Sequence of Acid Soils on the East Otago Up- lands" (New Zealand Journal of Experimental Agricul- ture [1984]: 119-129). Use the KW test and a .01 significance level to test the null hypothesis of no differ- ence in true mean phosphorus concentration for the four soil treatments. Treatment Concentration (mg/g) I 8.1 5.9 7.0 8.0 9.0 II 11.5 10.9 12.1 10.3 11.9 III 15.3 17.4 16.4 15.8 16.0 IV 23.0 33.0 28.4 24.6 27.7

The answer is: KW " 17.86, 0.17 exceeds the critical value of 11.34, reject H0 Please use SPSS 16.21 * The given data on phosphorus concentration in topsoil for four different soil treatments appeared in the article "Fertilisers for Lotus and Clover Establishments on a Sequence of Acid Soils on the East Otago Up- lands" (New Zealand Journal of Experimental Agricul- ture [1984]: 119-129). Use the KW test and a . 01 significance level to test the null hypothesis of no differ- ence in true mean phosphorus concentration for the four soil treatments. 16.21 The given data on phosphorus concentration in topsoil for four different soil treatments appeared in the article "Fertilisers for Lotus and Clover Establishments on a Sequence of Acid Soils on the East Otago Up- Iands" (New Zealand Journal of Experimental Agricul- ture [1984]: 119-129).
