### Question:
KruskalWallis { public static boolean test(TransposeDataCollection transposeDataCollection, double aLevel) { double pvalue = getPvalue(transposeDataCollection); boolean rejectH0=false; if(pvalue<=aLevel) { rejectH0=true; } return rejectH0; }  static double getPvalue(TransposeDataCollection transposeDataCollection); static boolean test(TransposeDataCollection transposeDataCollection, double aLevel);  }### Answer:
@Test public void testTest() { logger.info("test"); TransposeDataCollection transposeDataCollection = new TransposeDataCollection(); transposeDataCollection.put(0, new FlatDataCollection(Arrays.asList(new Object[]{82,93,86,87,99,95,93,89,96}))); transposeDataCollection.put(1, new FlatDataCollection(Arrays.asList(new Object[]{81,85,93,91,84,88,84,92,81,92}))); transposeDataCollection.put(2, new FlatDataCollection(Arrays.asList(new Object[]{97,85,83,93,88,86,90,94,87,93}))); transposeDataCollection.put(3, new FlatDataCollection(Arrays.asList(new Object[]{93,89,94,96,81,84,80,84,92}))); double aLevel = 0.05; boolean expResult = false; boolean result = KruskalWallis.test(transposeDataCollection, aLevel); assertEquals(expResult, result); }
