Percentage of Democratic Vote by Counties in Georgia
(a) Make a box-and-whisker plot of the data. Find the interquartile range.
(b) Grouped Data Make a frequency table using five classes. Then estimate the mean and sample standard deviation using the frequency table. Compute a 75% Chebyshev interval centered about the mean.
(c) If you have a statistical calculator or computer, use it to find the actual sample mean and sample standard deviation. Otherwise, use the values x = 2769 and x 2 = 132,179 to compute the sample mean and sample standard deviation.
