Chapter 10.2, Problem 35E
Solution

a.

To create: A frequency table for the data.

The frequency table is:

  ClassFrequency29.0−30.9231.0−32.9433.0−34.9535.0−36.9537.0−38.91

Given:

The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:

  33.5, 35.3, 33.8, 29.3, 36.7, 32.8, 31.7, 36.3, 33.5, 28.2, 34.8, 33.5, 35.3,29.7, 38.5, 32.7, 34.8, 34.2, 31.6, 35.4

Calculation:

Taking the class values as below:

  29.0−30.9,31.0−32.9,33.0−34.9,35.0−36.9,37.0−38.9

The frequency table is:

  ClassFrequency29.0−30.9231.0−32.9433.0−34.9535.0−36.9537.0−38.91

b.

To draw: A histogram for the data.

Given:

The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:

  33.5, 35.3, 33.8, 29.3, 36.7, 32.8, 31.7, 36.3, 33.5, 28.2, 34.8, 33.5, 35.3,29.7, 38.5, 32.7, 34.8, 34.2, 31.6, 35.4

Graph:

  PRECALCULUS:GRAPHICAL,...-NASTA ED., Chapter 10.2, Problem 35E

Interpretation:

By taking the frequency table as:

  ClassFrequency29.0−30.9231.0−32.9433.0−34.9535.0−36.9537.0−38.91

Here, “Frequency” is in Y-axis and “Salary” is in X-axis.

c.

To describe: The shape of the histogram.

The shape of the distribution is symmetric.

Given:

The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:

  33.5, 35.3, 33.8, 29.3, 36.7, 32.8, 31.7, 36.3, 33.5, 28.2, 34.8, 33.5, 35.3,29.7, 38.5, 32.7, 34.8, 34.2, 31.6, 35.4

Calculation:

From part b ,it can be seen that the values are symmetric with most salaries in the $33,000-36,999. interval.

Conclusion:

The shape of the distribution is roughly symmetric.
