'We have conducted a two-sided Z-test to assess the null hypothesis that the mean con- ents of soda cans is 330ml. The p-value of the test is 0.74, meaning that the probability of the null hypothesis statement being correct is 74%. As the p-value is much greater han the specified 5% type II error rate, it follows that the true mean soda can contents s indeed 330ml."
