1. scooby and shaggy want to open a dog-friendly bakery. they have created a new scooby snack
that they think will reduce the production of body gas associated with eating generic scooby
snacks from the bakery down the street. they recruit 100 dogstomers (dog customers) with a
history of gas problems. they have 50 of them (group a) eat scooby snacks with the new recipe.
the other 50 (group b) eat scooby snacks with the recipe that looks just like new formula but is
really just mixture of mayonnaise and food coloring. both groups were told that they were
getting the recipe that would reduce gas production. two hours after eating the scooby snacks
30 dogstomers in group a reported having fewer gas problems and 8 customers in group b
reported having fewer gas problems.
a. which is the control group?
b. what is the independent variable?
