a.
To explain: The reason behind bar graph will not work for these data.
The reason behind bar graph will not work for these data is the variable is not categorical.
Given:
The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:
Concept used:
Categorical variables place the individual data into a category.
Calculation:
The given data are all numerical.
Thus, the variable is quantitative and Bar graphs only can work for categorical variables.
Conclusion:
The reason behind bar graph will not work for these data is the variable is not categorical.
b.
To draw: A stem plot for this data set.
The stem plot is:
Given:
The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:
Concept Used:
Draw a vertical line.
Put the digits of the tens to the left of the vertical line and the digits of the ones of every data value to the right of the vertical line
Calculation:
The stem plot is:
c.
To describe: The shape of the distribution
The shape of the distribution is roughly symmetric.
Given:
The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:
Calculation:
From part
Also, there are two gaps in the stem plot which implies that there are few low and high outliers in the data.
Conclusion:
The shape of the distribution is roughly symmetric.
