Using the histograms, what is a correct comparison of public and private starting salaries?

Both salary distributions are skewed left.

In both groups, more than 10 percent of salaries are greater than $55,000.

The median salary for both groups is between $45,000 and $50,000.

Answer:

Explained below.

Step-by-step explanation:

Histogram is a graphical display of the data provided where the height of the bars represents the frequency of the values in a specific range.

The histograms can be used to draw conclusions about the shape of the distribution of the data provided.

  • A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution.

In the histogram, if maximum of the data-values are collected on the left of the chart then the distribution is positively skewed.

  • A distribution is known as to be skewed to the left, or negatively skewed, when maximum of the data are collected on the right of the distribution.

In the histogram, if maximum of the data-values are collected on the right of the chart then the distribution is negatively skewed.

  • A distribution is known as to be symmetric, when maximum of the data are collected on the middle of the distribution.

The frequencies provided can be converted into relative frequencies to determine what percentage of data is within a specific interval.

[tex]\text{Relative Frequency}=\frac{\text{Frequency of the group}}{N}\times100\%[/tex]

The formula of median is:

[tex]m = L + \left( \frac{\frac{N}{2} - F}{f}\right)C.[/tex]

Here,

L = lower class boundary of the group containing the median

N = total number of values

F = cumulative frequency of the groups before the median group

f = frequency of the median group

C = group width
