(b) In an experiment to investigate niacin retention in vegetables as a function of cooking temperature (A), sieve size (B), type of processing (C), and cooking time (D), each factor was held at two levels. Two blocks were used, with the allocation of blocks as given in part (a) to confound only the ABCD interaction with blocks. Use Yates's procedure to obtain the ANOVA table for the accompanying data. Assume that all three-way interaction effects are absent, so that the associated sums of squares can be combined to yield an estimate of o. (Round your answers to two decimal places.)
