9. The relative strengths of 150 silver solder welds are tested, and the results are given in the following table. Tally these figures and arrange them in a frequency distribution. Determine the cell interval and the approximate number of cells. Make a table showing cell midpoints, cell boundaries, and observed frequencies. Plot a frequency histogram. 1.5 0.1 0.3 3.5 1.7 1.8 2.2 3.1 1.5 1.9 2.9 1.8 1.2 2.9 0.7 1.1 3.2 2.3 1.2 2.1 1.9 1.7 1.8 2.1 3.1 1.3 1.0 1.3 2.4 1.5 0.7 0.5 3.0 1.7 3.3 3.1 1.3 3.5 2.0 1.5 1.4 1.6 1.4 1.4 3.0 3.0 1.4 0.9 0.7 2.6 0.7 1.6 2.8 3.3 2.3 2.8 0.9 2.6 3.3 2.1 1.3 1.7 2.1 1.4 2.2 2.9 2.5 2.8 3.1 1.0 2.4 1.5 13. Using the data of Exercise 9, construct: a. A relative frequency histogram b. A cumulative frequency histogram c. A relative cumulative frequency histogram 9.
