  1. 2 · The number above Miss is 2, so the ball missed twice.
  2. Try the ramp and watch the ball · Try the ramp and watch the result before choosing a change.
  3. False · Every try missed, so none got the ball into the cup. These tests did not meet the goal.
  4. Point the ramp toward the cup · Changing where the ramp points can change where the ball goes. Test again to see whether it reaches the cup.
  5. Change one part and test again · Zoe can use the misses to choose one change, then test whether it helps.
  6. Ramp A, with four hits in five tries · Both ramps had five tries. Ramp A had more hits, so it had better results in these tests.
  7. Yes, it had more hits than before · The new tests had four hits instead of one, with five tries each time. The new results were better.
  8. He has one result and needs more tests · The test shows one hit. It does not show what happens on other tries.
