How do I find actual probability when given mean weight in statistics?
Cans of salmon have a normal net weight of 250 g. However, due to variation in the canning process, the actual net weight has an approximate normal distribution with a mean of 255 g and a standard deviation of 10 g. According to Consumer Affairs, a sample of 16 tins should have less than a 5% chance that the mean weight is less than 250 g. What is the actual probability that a sample of 16 tins will have a mean weight less than 250 g?
