Answer:
The probability that the sample mean weight of these 400 bags exceeded 10.6 ounces is P(Xs>10.6)=0.
Step-by-step explanation:
When we take samples of size n=400, we have the folllowing parameters for the sampling distribution for the sample means:

We can calculate the probability that the sample mean weight of these 400 bags exceeded 10.6 ounces calculating the z-score for Xs=10.6 and then its probability P(Xx>10.6), using the standard normal distribution:
