27.31 describe situations in which we want to 2728 through n r eshonses in several populations. For each setting meao the and the response variable. Then give I, n, and 27.30 puu sque the degrees of freedom of the ANoVan n st sell products?

Twelve students were assigned to the taste group, 15 to the placebo group, and 16 to the control group. Ratings of perceived exertion (RPE) measured on standard 15-point scale rang scores were m 6 (very, very light) to 20 (exhausted),"
