Len [333]

Answer: 0.9738

Step-by-step explanation:

We assume that the scores follows a normal distribution.

Let $\overline{x}$ denotes the class average .

As per given we have,

$\mu=76\ \ \&\ \ \sigma=12$

Sample size : n= 12

The probability that a class of 15 students will have a class average greater than 70 on Professor Elderman’s final exam will be :

$P(\overline{x}>70)=1-P(\overline{x}$

Hence, the correct answer = 0.9738
