Problem 17E

The article “Filtration Rates of the Zebra Mussel (Dreissena polymorpha) on Natural Seston from Saginaw Bay, Lake Huron” (D. Fanslow, T. Nalepa, and G. Lang, Journal of Great Lakes Research 1995:489:500) reports measurements of the rates (in mL/mg/h) at which mussels filter seston (particulate matter suspended in seawater).

a.In the year 1992, 5 measurements were made in the Outer Bay; these averaged 21.7 with a standard deviation of 9.4Find a 95% confidence interval for the mean filtration rate in the Outer Bay.

b.In the year 1992, 7 measurements were made in the Inner Bay; these averaged 8.6 with a standard deviation of 4.5Should the Student’s t distribution be used to find a 95% confidence interval for the mean filtration rate for the Inner Bay? If so, find the confidence interval. If not, explain why not.

WELCOME TO CHEMISTRY 1127Q! Week One: Part A ****These notes are in-class notes from Chemistry 1127Q. Every bullet point was shown during a lecture with a white-board teaching style. UNITS: Unites tell you how to solve problems Skills You Need: Dimensional Analysis Significant Figures Metric Conversions ALL PUT UNITS IN. EVERYWHERE. Example: I run 5 and 6. but, 5 and 6 what Instead you should write I ran 5 miles in 6 hours. Ratios: Every ratio has a reciprocal Significant Figures: *Measurements have significant figures, they aren't infinite *There are limits of useful numbers
