(a) What is the population average causal effect of receipt of treatment B relative to receipt of treatment A in this population? (b) Fill in the last column of observed responses given treatment assignments and adherence. (You can just provide this as a list with values and subject numbers rather than reproducing the entire table.) (0) Find the ITT estimate of the causal effect of treatment. (d) (At least for placebo controlled trials) the ITT analysis is generally considered \"conservative\" in that it underestimates the full adherence treatment eect. Is that true in this case? Why or why not
