Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain." The acidity of liquids is measured by pH on a scale of 0 to 14. Distilled water has pH 7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so acid rain is sometimes defined as rainfall with a pH below 5.0. A sample of 105 rainwater specimens had mean pH 5.43; standard deviation 0.54; and five‑number summary 4.33, 5.05, 5.44, 5.79, 6.81.

(1) Compare the mean and median and also the distances of the two quartiles from the median.

Does it appear that the distribution is quite symmetric? Why?

a) The third quartile is closer to the median than the first quartile is. This indicates that the third quartile may have been pushed down by a right‑hand skew in the distribution.

b)The median is a relatively resistant measure, while the mean isn't. Therefore, the mean gets pulled further away from the direction of a long tail. Since the mean is lower than the median, we conclude that the distribution has a right‑hand tail.

c) The mean is almost identical to the median, and the quartiles are similar distances from the median. This suggests that the distribution is reasonably symmetric.

d) The mean is a relatively resistant measure, while the median isn't. Therefore, the median gets pulled further away from the direction of a long tail. Since the median is lower than the mean, we conclude that the distribution has a right hand tail.

(2a) If the distribution is really ?(5.43,0.54), what proportion of observations would be less than 5.05? (Enter your answer rounded to four decimal places.)

(2b)If the distribution is really ?(5.43,0.54), what proportion of observations would be less than 5.79? (Enter your answer rounded to four decimal places.)  

(3) Do these proportions suggest that the distribution is close to Normal? Why?

a) These proportions do not provide information about Normality.

b)No, because the Normal distribution has a lower first quartile and a lower third quartile.

c)Yes, because the quartiles are very close to the quartiles of the Normal distribution.

d)No, because the Normal distribution has a higher third quartile and a higher first quartile.

Taxing markets where consumers and producers are relatively ____________ to price changes will generate the most tax revenue because the equilibrium quantity after the tax will ________________ after the tax is imposed.

The FDA tries to protect us as consumers. You may take for granted the changes they have enacted to protect us. For example, the surgeon general warning notices on the side of cigarettes... yup they came as a result of regulations to protect us.

Question: We have an extremely diverse class. Most of us are first generation immigrants, or have close ties to another country. Either way, think of a country which you love and have a close affiliation to (other than USA). Does your country have any laws and regulations that protect the consumer? If so, can you provide one as an example? If not, explain why your country does not have them.

Discuss: If you were a leader of a company going overseas, would you take advantage of weak protection laws or bring the stricter regulations into the country to guide your service or product in that country?
