The result of a hypothesis is described in terms of the probability of obtaining a particular sample. Use the given context to formulate the null and alternative hypotheses. Discuss whether the sample provides evidence for rejecting the null hypothesis.A consumer group believes that the mean volume of juice in a company's 24 ounce juice bottles is actually less than 24 ounces.In a random sample of 310 bottles, the mean volume of juice was 23.9 ounces. Assuming that the mean volume of juice for all the company's 24-ounce bottles is 24 ounces, the probability of selecting a random sample with a mean volume of 23.9 ounces or less is 0.00017.
