Records from previous years show the proportion of registered voters that voted in previous elections for each district. A political analyst wants to see if those proportions have changed for this year's upcoming elections. The political analyst randomly samples 136 registered voters and asks them which district they live in and if they have voted yet.

Business expenses tend to follow Benford's Law, because there are generally more small expenses than large expenses. Perform a "Goodness of Fit" ChiSquared hypothesis test (oz 2 0.05) to see if these values are consistent with Benford's Law. If they are not consistent, it there might be embezzelment.
