Hello,

What test would I perform to answer this question? ) Can the researchers conclude that age impacts the amount of reduction in each of your assigned measures? (cholesterol and fat intake)

I am a bit confused about whether to use a t-test of two means or a two-way ANOVA?

here is the data. I've calculated the difference between pre- and post-program measures.
