A machine in the lodge at a ski resort dispenses a hot chocolate drink. The average cup of hot chocolate is supposed to contain 7.75 ounces. We may assume that x has a normal distribution with a standard deviation of 0.3 ounce. A random sample of 16 cups of hot chocolate from this machine show the average content to be 7.62 ounces. Do you think the machine is out of adjustment and the average amount of hot chocolate is less than it is supposed to be? Use a 5% level of significance. Find the P-value.
