Answer:
Yes, because the population distribution is normally distributed, and we have a random sample.
Step-by-step explanation:
If the population is skewed, then the sample mean won't be normal for when N is small.
If the population is normal, then the distribution of sample mean looks normal even if N = 2.
If the population is skewed, then the distribution of sample mean looks more and more normal when N gets larger.
Since we have use 33% of the student, then N is large enough to conclude that the student are bad at guessing
