Answer:
0.0228, Hope that useful for you.
Step-by-step explanation:
Because of " the scores...normally distributed of a mean 310 and the standard deviation 12", we can use the Central limit theorem.
That means:
([tex]P(X>334)= P(\frac{X-E(X)}{SD(X)}>\frac{334-310}{12})= P(Z>2)= 1-P(Z\leq 2)= \\1- 0.9772= 0.0228[/tex]
