A vending machine dispenses coffee, and a random sample of 27 filled cups have contents with a mean of 7.14 oz and a standard deviation of .17 oz. Use a .05 significance level to test the claim that the true mean fill for all cups is greater than 7 oz. You may assume a normal population (n < 30 here; assume that assumption was checked). Fill in and show calculations. Ho : null hypothesis S.V.: sample value Ha :...

A machine in the lodge at a ski resort dispenses a hot chocolate drink. The average cup of hot chocolate is supposed to contain u = 8 ounces. We may assume that x follows a normal distribution with standard deviation r = 0.3 ounces. A random sample of 16 cups of hot chocolate from this machine had a mean content of x bar = 7.5 ounces. Use a a = 0.05 level of significance and test whether the mean amount...

Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 24 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.09 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 12.04 oz and 12.56 oz, the range rule of thumb can be...

1. A vending machine that dispenses coffee into cups must fill the cups with 7.8 oz of liquid. Before selling the vending machine to a college or business, the company tests the machine to be sure it is dispensing an average amount of 7.8 oz of coffee. A sample of 20 amounts is shown here. Assume that the amount of coffee dispensed is normally distributed. 7.78 7.79 7.82 7.82 7.87 7.84 Ounces Dispensed 7.80 7.80 7.83 7.85 7.82 7.78 7.75...
