The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with mean of 3.2 pounds and standard deviation of 0.8 pound. If a sample of 4 fish is taken. What is the probability that the sample means will be more than 3.4 pounds?

Step-by-step explanation:

Relevant Data provided according to the question is as follows

= 3.2

= 0.8

n = 4

According to the given scenario the calculation of probability that the sample means will be more than 3.4 pounds is shown below:-

Now, we will solve the formula to reach the probability that is

= 1 - 0.6915

= 0.385

Therefore the correct answer is

So, for computing the probability we simply applied the above formula.
