A consumer testing service tested whether the average baking time of whole wheat bread in gas ovens was less than the average baking time of whole wheat bread in electric ovens. Ten loaves of whole wheat bread were prepared and five were randomly assigned to be baked in the five randomly selected gas ovens and five were randomly assigned to be baked in the five randomly selected electric ovens.2. What is the explanatory variable, and is it quantitative or categorical?type of oven (gas versus electric) which is categoricalbaking time which is quantitativebaking time which is categoricaltype of oven (gas versus electric) which is quantitativetype of bread which is categoricaltype of bread which is quantitative3.
