Statistical test to infer if brand preference depends on income
You are going to need to know the sample size as well and multiply it back out from the percentages into frequency counts.

After that, my suggestion is you do a Chi Square Test for independence, since you have two categorical variables.

Either that or you can do an ANOVA (you technically have 3 variables: something for the percentage like a yes/no, brand, and income) , but you'll have to structure you data differently to do that and you will need the sample detail. You'll also need to convert your categorical variables into dummy variables.
