Question 382365: Please show me how to complete this problem:
Cheese weighs 8 oz, has a normal distribution mean of 8.1 oz, and a standard deviation of 0.1 oz.
There is a 5% chance the average weight of 5 samples will be below?
I said 8.03 oz. Is this correct?
Also, if 5 cheeses were selected, what would the probability that they are less than 8 oz?
I said 0.9873. Is this correct?
