Answer:
Step-by-step explanation:
Let X be the random variable that represents a score of Susan. We know that X has a normal distribution with average score of 225 and a standard deviation of 13. For n = 16 games, the average score
has a normal distribution with mean of 225 and a standard deviation of
. Besides, the z-score related to 220 is (220-225)/3.25=-1.5385, and the z-score related to 228 is (228-225)/3.25= 0.9231. Therefore, we are looking the probability
= 0.76
2000, since it’s above 1500
