A limnologist is studying a Minnesota lake in October. He records the temperatures in °C for surface water taken every other day at noon. The data are shown below.
8.5 8.1 7.9 9.0 7.7 7.3 7.1 6.8 9.2
6.8 6.3 7.0 6.5 5.7 5.9 4.9 4.2 6.9
a. Construct a stem and leaf plot to display the distribution of the data.
b. Would you describe the distribution of the data as symmetric, skewed to the right or skewed to the left?
______________
c. Explain.

Stem And Leaf Plot
A graphical representation used in descriptive statistics to display quantitative data where each data point is split into a "stem" and a "leaf."
Limnologist
A scientist who specializes in the study of inland waters, including the biological, chemical, physical, and geological characteristics and processes of lakes and rivers.
Surface Water Temperatures
The temperatures recorded at the surface of bodies of water, such as lakes, rivers, and oceans, which can vary widely based on geographical location, season, and time of day.
- Gain insight into the employment and interpretation of various types of graphical data depictions, like stem-and-leaf plots, bar charts, pie charts, and dot plots.
- Evaluate the distribution of data using graphical methods and recognize patterns such as skewness or symmetry.

Final Answer :
2, 9; 7, 9; 3, 5, 8, 8, 9; 0, 1, 3, 7, 9; 1, 5; 0, 2; Symmetric; The distribution seems to be symmetric since the left and right sides of the distribution, when divided at the middle value, form mirror images.
