3. Suppose you are studying the distribution of zinc in a lake and want to know if there is a significant difference between the concentration of Zn²+ at the sediment-water interface and its concentration at the air-water interface. You collect samples from six locations-near the lake's center, near its drainage outlet, etc.-obtaining the results (in mg/L) shown in the table. Using this data, determine if there is a significant difference between the concentration of Zn²+ at the two interfaces at. Complete this analysis treating the data as paired.

Chlorophylls a and b are plant pigments that absorb sunlight and transfer the energy into photosynthesis of carbohydrates from CO2 and H2O, releasing O2 in the process. Chlorophylls were extracted from chopped up grass and measured by spectrophotometry. The table shows results for chlorophyll a for four separate analysis of five blades of grass. Chlorophyll a (g/L) Blade 1 Blade 2 Blade 3 Blade 4 Blade 5 1.09 1.26 1.1 1.23 0.85 0.86 0.96 1.21 1.3 0.65 0.93 0.8 1.27 0.97 0.86 0.99 0.73 1.12 0.97 1.03 Four replicate measurements for each blade of grass tell us the precision of the analytical procedure (sanalysis). Differences between mean values for each of the five blades of grass are a measure of variation due to sampling (ssampling). Using Excel and it’s ANOVA function, find the standard deviations attributable to sampling and to analysis, as well as the overall standard deviation arising from both sources.
Plants emit gases that trigger the ripening of fruit, attract pollinators, and cue other physiological responses. A study examined factors that affect the emission of volatile compounds by a type of potato plant. The volatile compounds analyzed were hydrocarbons used by other plants and animals. Following are data on plant weight (x), in grams, and quantity of volatile compounds emitted (y), in hundreds of nanograms, for 11 potato plants.
