Question

Statistics/ Algebra 2

Answer 1

Grandiosa Pizza is considering a recipe change. Researchers from Grandiosa Pizza must determine whether consumers are more or less likely to buy pizza with heavy spices or light spices. The researchers realize that the subjects might not like the heavy spices after tasting a pizza with light spices and vice versa.

How should the researchers decide which pizza should be tasted first?

A. Mild pizza should always be tasted first because no one will be able to taste anything after the spicy test.
B. Mild pizza should always be tasted second because it will be a relief after the spicy pizza.
C. There should be only one type of pizza per test to avoid confusing the subjects.
D. The researchers should flip a coin to decide independently for each subject, to randomly assign the spicy or mild pizza in each experimental unit.
E. There should be only one pizza available for each subject to avoid confusing people.
