Given in the question that, Drug dealer motivation is traditionally attributed to greed or social pressures. Researchers R. Highland and D. Dabney explore possible personality characteristics as a motivation in the article "Using Adlerian Theory to Shed Light on Drug Dealer Motivations" (Applied Psychology in Criminal Justice, Vol. 5, Issue 2, pp. 109-138). The following table lists the types of drug sold from a sample of convicted drug dealers.

We need to obtain a relative -frequency Distribution.

The relative frequency table is:

The general formula for the relative frequency is,

$\text{Relative Frequency}=\frac{\text{Frequency}}{\text{Total frequency}}$

Substituting$"73"$as the class level drug sold frequency and $"226"$as the total number of class level drug sold frequency in relative frequency.

Relative Frequency of sold drug marijuana $=\frac{73}{226}$

$=0.3230$

Similarly, the relative frequency for the remaining faculty rankings are as follows:

Given in the question that, Drug dealer motivation is traditionally attributed to greed or social pressures. Researchers R. Highland and D.

The following table lists the types of drug sold from a sample of convicted drug dealers.

We need to draw a pie chart.

Output using MINITAB software is given below:

When the relative frequency is multiplied by the degree$360$, the pie slice for each type for the robbery is obtained.

Determining the pie chart slice size for sold drug marijuana:

pie slice for sold drug marijuana $=0.3230×360$

$=116.28$

Similarly, the pie slices for the remaining types of sold drugs are obtained below:

Proportion is calculated by the product of relative frequency of each class with $100.$

Proportion for sold drug marijuana $=$relative frequency $×100$

$=0.3230×100$
$=32.3$

Similarly, the proportion for the remaining sold drugs are obtained below:

Software procedure:

Step by step procedure to draw the pie chart using MINITAB software.

• Choose Graph > Pie Chart.
• Enter the columns of drug sold in Categorical variables.
• In Summary variables, enter the corresponding column.
• Click OK.

The following table lists the types of drug sold from a sample of convicted drug dealers.

We need to construct a bar chart.

• Output using MINITAB software is given below:

Software procedure:

Step by step procedure to draw the bar chart using MINITAB software.

• From Bars represent, choose Values from a table.
• Under One column of values, choose Simple. Click OK.
• Choose Simple, and then click OK.
• In Graph variables, enter the column of drug sold.
• In Categorical variables, enter the column of percent.
• Click OK.

Thus, the bar chart is constructed for the location of the cities.
