Hi! I have been working on this all day. I am hoping that someone can explain it.

` The table below is the result of an experiment by Zelazo and Zelazo ( 1972; to see the effect of training on the walking age ( in months ) of newborns . Active group had their walking and placing reflexes trained during four three- minute sessions that took place every day from their second to their eighth rock of life . Passive training group received the same types of social and gross motor stimulation , but did not have their specific walking and placing reflexes trained . No training group had no special training , but were tested along with the children who underwent active or passive training . Eighth- weck control group had no training and were only tested at the age of & Rocks .` Group* Active Passive `Hone Control . giv 9.00 11.00 11.50 13.25 9.50 10.00 12.010 11.50 9. 75 10.010 4. 0^ 12.010 10.00 11.75 11.50 13.501 12.010 10.50 13:20 11.50 4. 50 15. 010 13.00 (a ) Test to see if there is walking age difference among the four different groups . For this test , specify the null and alternate hypotheses construct an ANOVA table` specify the appropriate critical value for the test . What conclusion can you make regarding the test ? State your answer in the context of the problem ( use # =. ! ). ( b) Use the Banferroni correction to construct boy's multiple comparison confidence intervals for the differences in mean of age for each pair of groups . Interpret the results , and indicate which groups are different in walking age
