Respondents are asked to select their preference between brand A and brand
B. If we want to test the null hypothesis that the number of people who prefer brand A is equal to the number of people who prefer brand B, we would conduct an independent-sample t-test.

An independent-sample t-test is used to compare the mean scores of two different groups, not to compare the number of people with a certain preference. The appropriate test for comparing proportions or percentages is the chi-square test or Fisher's exact test.
