According to the Official Stage Magician Handbook, magic rábbit weight (Ibs.) is normally distributed with u = 6.2 and o = 1.5. Consider obtaining a random sample of 337 magic rabbits. Would it be unusual for the sample mean to be at least 6.5? Why or why not?

Question
According to the Official Stage Magician Handbook, magic rabbit weight (Ibs.) is normally distributed with u = 6.2 and o = 1.5. Consider obtaining a random sample of 337 magic rabbits. Would it be unusual for the sample mean to be at least 6.5? Why or why not? O No because the z-score corresponding to a sample mean of 6.5 would be z = 0.20. O Yes because the z-score corresponding to a sample mean of 6.5 would be z = 3.67. O Yes because the z-score corresponding to a sample mean of 6.5 would be z = 0.20. No because the z-score corresponding to a sample mean of 6.5 would be z = 3.67.
