Answer:
No, although the random and large counts conditions are met, the 10% condition is not met.
Step-by-step explanation:
The random condition is met because the student selects a random sample of 50 seniors. The large counts condition is met because there are 38 expected successes and 12 expected failures, which are both at least 10. The 10% condition is not met because n = 50 is not less than 10% of the size of the population (N = 274 seniors).
