Chapter 2.7, Problem 2.119ACI
Permeability of sandstone during weathering. Refer to the Geographical Analysis (Vol. 42, 2010) study of the decay properties of sandstone when exposed to the weather. Exercise 2.77 (p. 86). Recall that slices of sandstone blocks were tested for permeability under three conditions: no exposure to any type of weathering (A), repeatedly sprayed with a 10% salt solution (B), and soaked in a 10% salt solution and dried (C).
- a. Identify any outliers in the permeability measurements for Group A sandstone slices.
- b. Identify any outliers in the permeability measurements for Group B sandstone slices.
- c. Identify any outliers in the permeability measurements for Group C sandstone slices.
- d. If you remove the outliers detected in parts a-c, how will
descriptive statistics like the mean,median , and standard deviation be affected? If you are unsure of your answer, carry out the analysis.

Environmental conditions can affect the growth of coral. To study this, a researcher examined a species of coral that is found in
the Caribbean Sea and the Gulf of Mexico. At 12 localities, he determined the average annual calcification rate of coral over a
period of several years and the average annual maximum sea surface temperature during the same period. Calcification rate
affects the growth of coral, with higher rates corresponding to greater growth. The table contains data for these 12 localities.

Complete parts a and b. a. Do the values of SSE and R suggest that the model provides a good fit to the data? Explain. A. Yes. Since R = 0.94 is close to 1, this indicates the model provides a good fit. Also, SSE = 0.33 is fairly small, which indicates the model provides a good fit. B. There is not enough information to decide. No. Since R = 0.94 is close to 1, this indicates the model does not provide a good fit.

- Researchers collected data to examine the relationship between pollutants and preterm births in Southern California. During the study air pollution levels were measured by air quality monitoring stations. Specifically, levels of carbon monoxide were recorded in parts per million, nitrogen dioxide and ozone in parts per hundred million, and coarse particulate matter PM10 in µg/m3. Length of gestation data were collected on 143,196 births between the years 1989 and 1993, and air pollution exposure during gestation was calculated for each birth. The analysis suggested that increased ambient PM10 and, to a lesser degree, CO concentrations may be associated with the occurrence of preterm births. a. The paragraph above describes an O A.
