Considering a significance level of alpha = 0.05, select the correct statement below.
%3D
For region, all pairwise Region levels differ from each other significantly with regards to survey responses.
For design, all pairwise Design levels differ from each other significantly with regards to survey responses.
The average survey response using Design 3 is 175.58 higher than the average survey response using Design 2.
Designs 1 and 3 do not differ significantly; but Design 2 is significantly different than Design 1, and Design 2 is significantly different than Design 3 with regards to
survey responses.
