Answer:
The probability that the average of the scores of all 400 students exceeds 19.0 is larger than the probability that a single student has a score exceeding 19.0
Step-by-step explanation:
Xi~N(18.6, 6.0), n=400, Yi~Ber(p); Z~N(0, 1);
P(Xi≥19.0)=0.473
p=0.473
Yi~Ber(0.473)
Based on the Central Limit Theorem:
Then:
Based on the Central Limit Theorem:
Then:
the probability that the average of the scores of all 400 students exceeds 19.0 is larger than the probability that a single student has a score exceeding 19.0
