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.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
