How sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures and coral growth per year at locations in the Gulf of Mexico and the Caribbean Sea. Scientists examined data on mean sea surface temperatures (in degrees Celsius) and mean coral growth (in centimeters per year) over a several‑year period at locations in the Gulf of Mexico and the Caribbean. The table shows the data for the Gulf of Mexico.

Shortleaf Pines. The ability to estimate the volume of a tree based on a simple measurement, such as the diameter of the tree, is important to the lumber industry, ecologists, and conservationists. Data on volume, in cubic feet, and diameter at breast height, in inches, for 70 shortleaf pines was reported in C. Bruce and F. X. Schumacher’s Forest Mensuration (New York: McGraw-Hill, 1935) and analyzed by A. C. Akinson in the article “Transforming Both Sides of a Tree” (The American Statistician, Vol. 48, pp. 307–312). The data are provided on the WeissStats site. a. obtain and interpret the standard error of the estimate. b. obtain a residual plot and a normal probability plot of the residuals. c. decide whether you can reasonably consider Assumptions 1–3 for regression inferences met by the two variables under consideration.
A histogram titled "20 Busiest North American Airports" has a horizontal axis labeled "Total Passengers (Millions)" and a vertical axis labeled "Frequency" with values from 0 to 10. The histogram has 8 bars. Each bar is associated with a label and an approximate value as listed below. Frequency 10 O 0 7 02 8 3 30-39.9 20 Busiest North American Airports 40-49.9 50-59.9 Total Passengers (Millions) What is the lowest frequency value? 60-69.9 70-79.9 80-89.9 90-99.9 100-109.9
The age of a tree can be determined by counting each annual growth ring in the trunk of the tree. A common measure of the size of a tree is the "diameter at breast height" DBH. "Breast height" is defined as 4 ½ feet above the uphill side of the tree. Consider the following data on 12 northern red oaks from southwestern Wisconsin: 11 15 28 1.5 1.0 6.0 45 12 52 16.5 11.0 | 10.5 9.0 Age(years) | 97 93 88 81 75 57 1.0 DBH(inch) | 12.5 12.5 8.0 9.5 d) What is the range of validity of this model?
Fahrenheit is the measurement of temperature commonly used in the US. On the Fahrenheit scale, water freezes at 32 F and boils at 212 F (at sea level). What is the data type and measurement scale of a dataset that records Fahrenheit temperature? a. Numerical and ratio b. Numerical and interva c. Categorical and ratio d. Categorical and ordinal
Determine which of the four levels of measurement ( norminal, ordinal, interval, ratio) is most appropriate for the data below. Years in which U.S. presidents were inaugurated
In the accompanying data table, the entries are for five different years and consist of the weights (metric tons) of lemons imported from another country and car crash fatality rates per 100,000 population. The data are based on data from a scientific publication. Lemon Imports: 220 274 355 478 539 Crash Fatality Rate: 16.7 14.8 15.2 14.7 15.8 Given that the data are matched and considering the units of the data, does it make sense to use the difference between each pair of values? Why or why not? Choose the correct answer below. A. No, it does not make sense to use the difference between each amount of lemon imports and car crash fatality rate in the same column,because the terms should be added. B. Yes, it does make sense to use the difference between each amount of lemon imports and car crash fatality rate in the same column, because they are measurements obtained from the same year. C. No, it does not make…
