The owner of a factory that sells a particular bottled fruit juice claims that the average capacity of their product is 250ml. To test the claim, a consumer group gets a sample of 100 such bottles, calculates the capacity of each bottle, and then find the mean capacity to be 248 ml. The standard deviation s is 5ml. Is the claim true at α=0.05?
