1. The average Belgian person drinks approximately 30 gallons of soda a year. Some Belgian legislators are considering instituting a sales tax on soda to raise revenue and possibly fight obesity. Will a sales tax on soda reduce the mean amount of soda consumed? A sales tax is added to a random sample of communities to measure the effect on soda consumption.

1. State the null and alternative hypotheses:

2. If sample results give a p-value of 0.019, what is your general conclusion regarding whether to reject or not reject the null hypothesis?

3. In the context of this situation, explain your conclusion.

20 liters of water at 20 bar and 100 °C are in a variable volume container. 56,000 kJ of heat are added to the system at constant pressure which causes an increase in both temperature and volume.

Draw a schematic of the process

Write the energy balance for this process and clearly state any assumptions:

What is the final volume of the container?

How much work in [kJ] is completed? Pay careful attention to your negative signs!

In one sentence explain your answer from Part D in the context of the process described in the problem statement and the heat that is added to the system.

In a test of the effectiveness of garlic for lowering​ cholesterol, 64 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes​ (before minus​ after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 0.2 and a standard deviation of 1.86. Use a 0.01 significance level to test the claim that with garlic​ treatment, the mean change in LDL cholesterol is greater than 0.What do the results suggest about the effectiveness of the garlic​ treatment? Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim.

In a test of the effectiveness of garlic for lowering​ cholesterol, 81 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes​ (before minus​ after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 0.9 and a standard deviation of 2.25 . Use a 0.10 significance level to test the claim that with garlic​ treatment, the mean change in LDL cholesterol is greater than 0 . What do the results suggest about the effectiveness of the garlic​ treatment? Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim
