Foundation November 2017 Paper 1 Q8
8 72 students each took a theory test followed by a practical test.
They either passed or failed each test.
This frequency tree shows some of the results.
(a) How many students passed both tests? [1]
(b) \(\dfrac{5}{6}\) of the 72 students passed the theory test.
Complete the frequency tree. [4]
(c) Which test was passed by more students?

| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| 60 8 12 3 | 4 | B1 for each correct value OR B1 for 60 B1FT for 12 B1FT for 8 and 3 | Answers must be integers Mark to candidate’s advantage |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Practical test because 61 > 60 (Comparison explicitly seen) | 3 | B1 for 61 or 52 + 9 or 84.7[2…]% or 85% [for practical] B1FT for their 60 or their 83[.3…]% [for theory] B1FT for correct conclusion based on their figures in the table, must see comparison | Accept denominator of 72 FT from their diagram, must give numerical values |
