The Citrus Council of America wants to determine whether consumers prefer plain orange juice or juice with some orange pulp in it. A random sample of 212 consumers was selected. Each member of the sample tasted a small, unlabeled cup of one kind and then tasted the other kind. Twelve consumers said they had no preference, 40 preferred plain juice, and the remainder liked the juice with pulp better. Test at the .05 level that the preferences for plain juice and for orange juice with pulp are equal.
