Chapter 16.3, Problem 21E

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 Uplands” (New Zealand Journal of Experimental Agriculture [1984]: 119–129).

Use the KW test and a 0.01 significance level to test the null hypothesis of no difference in true mean phosphorus concentration for the four soil treatments.

Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver’s head during a crash test is equal for each types of car. Use α = 5%.  Compact Midsize Full-size 643 655 702 680 672 469 427 525 495 483 484 465 402 476 435   State the null and alternate hypothesis for the data.  Given the results, what will be the conclusion of the team?

The yield of alfalfa from a random sample of six test plots is 1.4, 1.6, 0.9, 1.9, 2.2,and 1.2 tons per acre. Assume the data can be looked upon as a sample from anormal population. Test at the 0.05 level of significance whether this supports thecontention that the average yield for this kind of alfalfa is 1.5 tones per acre.
