Two randomly assigned participants are used in each cell (considerably more participants would be required for a practical study). The results, given below, are numbers of words correctly recognized. 
(a) Compute and for each cell and display these values in a table. 
(b) Proceed to obtain

(c) Compute the variance estimates; perform the three F tests at and and draw statistical conclusions. Display your results in a summary analysis of variance table. 
(d) Construct a table showing cell and marginal means. Considering the F-test results, which means would be of interest? Why? Draw final conclusions concerning the treatment variables.
