Measures of the Spread of the Data · Example 2

Use the following data (first exam scores) from Professor Dean's spring pre-calculus class:
33; 42; 49; 49; 53; 55; 55; 61; 63; 67; 68; 68; 69; 69; 72; 73; 74; 78; 80; 83; 88; 88; 88; 90; 92; 94; 94; 94; 94; 96; 100

(a) Create a chart containing the data, frequencies, relative frequencies, and cumulative relative frequencies to three decimal places.
(b) Calculate the following to one decimal place using a TI-83+ or TI-84 calculator:
(a) The sample mean
(b) The sample standard deviation
(c) The median
(d) The first quartile
(e) The third quartile
(f) IQR
(c) Construct a box plot and a histogram on the same set of axes. Make comments about the box plot, the histogram, and the chart.

Its source prints no answer for this problem, so there's nothing to check against.
