Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation, also called standard error 
In this problem, we have that:

What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error
