Explanation:

1. How many students took the test?

Step1: Count leaves per stem

• Stem 5: 2 leaves (6,6)
• Stem 6: 2 leaves (3,8)
• Stem 7: 7 leaves (1,2,6,7,8,8,8)
• Stem 8: 6 leaves (0,1,3,5,6,7)

Step2: Sum the counts

$2 + 2 + 7 + 6 = 17$

Step1: Identify smallest stem-leaf

Smallest stem is 5, smallest leaf on stem 5 is 6. So score is $56$.

Step1: Identify largest stem-leaf

Largest stem is 8, largest leaf on stem 8 is 7. So score is $87$.

Answer:
