Measurements of the percentage soil moisture are made on the top of a sloping field (X1), the side of the slope (X2), and at the bottom of the slope (X3). Using a 1% level of significance, determine whether or not the soil moisture characteristics are constant over the field.

X1 9.6 10.3 8.8 8.5 10.4 X2 15.2 19.7 14.4 11.6 17.0 X3 16.5 18.3 16.9 20.2 17.7 10-30. Test the null hypothesis of equality of group variances for both of the sets of three groups given below. Use a level of significance of 1%. What do the two tests show?

Set 1 Set 2 Group 1 1 2 3 4 1 2 3 4 Group 2 2 3 4 5 11 12 13 14 Group 3 3 4 5 6 21 22 23 24 10-31. For the given data set, which consists of three treatments and five blocks, use a 5% level of significance to test the significance of the treatment and block effects.
