2. Pigeons were trained to peck to obtain food. During extinction, one group of 21 pigeons was given a drug that inhibits the protein metabolism necessary for memory, while another group of 21 pigeons was not. The rate of pecking was then analyzed (use a one-tailed test). Does the drug increase the pigeons' pecking behaviour?

(a) What test would be used to analyze these data?
(b) What is the Ho?
(c) What is the H1?
(d) How many df are there in total?
(e) Given *=0.05, what is the critical value of t? (use a one tailed test)
(f) Would an obtained value of t of 1.62 lie within the rejection region?
(g) Does the treated group peck at a significantly higher rate (given t = 1.62)?
(h) This result would be reported as t ( ___ ) = _______, p _____ 0.05, r2=

I have completed a-g. Can you check it please? Can you show me how to do g and h? And, if there is anything wrong, can you please explain?
