Final answer:
Option (b) supports the hypothesis that a flat-bottomed boat is more stable than a v-shaped boat since it tips at a lesser degree.
Step-by-step explanation:
According to the hypothesis that a flat-bottomed boat is more stable than a v-shaped boat, we are looking for data that show the flat-bottomed boat tipping at a smaller angle from the center compared to the v-shaped boat. Option (b), where the flat bottom boat tips at 30 degrees from center and the v-shaped boat tips at 35 degrees from center, fits the hypothesis because the flat-bottomed boat requires a smaller angle to tip, indicating greater stability.
