1. The owner of a factory that sells a particular bottled fruit juice claims that
the average capacity of a bottle of their product is 250mL and standard
deviation of 3 ml. A random sample of 50 bottles of fruit juice have a mean
volume of 245 ml. At a level of significance of 5%, is there a sufficient
evidence to the support the claim of the owner?
