You are a manager for Company ABC and decide to compile data and analyze your employees’ level of satisifaction. You create a survey to ask each employee to rate their level of satisfaction working at Company ABC. Table 1 shows data of 15 people employees that responded to your survey.

Ethnicity Frequency White African American Hispanic • Using the Ethnicity frequency table (from part A), create a pie chart for Ethnicity of employees. Make sure to include a title and each slice is clearly labeled. Paste your Pie Chart below. (See video links on the last page of this document if needed) • Using the Ethnicity frequency table (from part A), create a bar graph for Ethnicity of employees. Make sure to include a title your graph and label each axis. • Do you think the pie chart, or the bar graph displays the differences in the data more clearly for the Ethnicity variable?

Frequency Distribution 30-39 40-49 50-59 60-69 • Create a histogram of the Age data for the Sale Representatives. Paste your graph below. • In 2-3 sentences, describe the shape of the histogram in part A. Would this be considered a symmetric or skewed? If skewed, describe the skewness. 7. Continue to focus on Age variable (Column E). • Calculate the 5-number summary for Age (Column E). Paste the summary below.
