An electric eel (electrophorus electricus) can produce a shock of up to 600 v and a current of 1 a for a duration of 2 ms, which is used for hunting and self-defense. to perform this feat, approximately 80% of its body is filled with organs made up by electrocytes. these electrocytes act as self-charging capacitors and are lined up so that a current of ions can easily flow through them.

a) how much charge flows through the electrocytes in that amount of time?
b) if each electrocyte can maintain a potential of 100 mv, how many electrocytes must be in series to produce the maximum shock?
c) how much energy is released when the electric eel delivers a shock?
d) with the given information, estimate the equivalent capacitance of all the electrocyte cells in the electric eel.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
