Let group 1 be people from Canada and group 2 be people from Sweden.           (a) Give notation for the quantity that is being estimated. Your answer should be an expression composed of symbols: -,=,≠,<,>,μ,μ1,μ2,p,p1,p2,ρ,p^,p^1,p^2,r.   Edit             (b) Give notation for the quantity that gives the best estimate. Your answer should be an expression composed of symbols: -,=,≠,<,>,μ,μ1,μ2,p,p1,p2,ρ,p^,p^1,p^2,r.
