Dixie Do-nuts is considering expanding from North Carolina into Tennessee, where the competing doughnut chain Gimme Sugar is based. A market research firm did a blind tasting study in each state to test the hypothesis that the proportion preferring Dixie Do-nuts to Gimme Sugar is the same in both places.

Based on a 0.05 significance level, which of the following conclusions can be drawn?
A. The study did not find a statistically significant difference in doughnut preferences between the two states.
B. More people prefer Dixie Do-nuts in North Carolina than in Tennessee.
C. The data prove that the alternative hypothesis is true.
D. Expanding into Tennessee would be a waste of resources.
