A randomized block design yielded the following partial ANOVA table. a. Find the sum of squares for the treatments and the error term. b. Find the mean of squares for the treatments and the blocks. c. Specify the null and alternative hypotheses you would use to compare the treatment means. d. What test statistic should […]

Commercial eggs produced from different housing systems. Refer to the Food Chemistry (Vol. 106, 2008) study of four different types of egg housing systems, Exercise 9.33 (p. 546). Recall that you analyzed the data file and discovered that the mean shell thickness (millimeters) differed for cage, barn, free range, and organic egg housing systems. A […]

A randomized block design was used to compare the mean responses for three treatments. Four blocks of three homogeneous experimental units were selected, and each treatment was randomly assigned to one experimental unit within each block. The data are shown below, followed by an SPSS ANOVA printout for this experiment b. Do the data provide […]

Suppose an experiment employing a randomized block design has four treatments and nine blocks, for a total of 4  9 = 36 observations. Assume that the Total Sum of Squares for the response is SS1Total2 = 500. For each of the following partitions of SS(Total), test the null hypothesis that the treatment means are equal […]
