To answer the questions, we will analyze the provided data about the salaries of employees at the four companies. ### Given Data: - **Company A**: Mean salary = \$27,000, Range = \$65,000 - **Company B**: Mean salary = \$36,000, Range = \$63,000 - **Company C**: Mean salary = \$34,000, Range = \$59,000 - **Company D**: Mean salary = \$35,000, Range = \$60,000 ### (a) Which company's salaries have the least variability? To determine the variability of salaries, we can use the range as a measure of variability. The smaller the range, the less variability there is in the salaries. - **Company A**: Range = \$65,000 - **Company B**: Range = \$63,000 - **Company C**: Range = \$59,000 - **Company D**: Range = \$60,000 **Comparison of Ranges:** - Company A: \$65,000 - Company B: \$63,000 - Company C: \$59,000 (least variability) - Company D: \$60,000 **Conclusion for (a)**: Company C has the least variability in salaries. ### (b) Which company has the highest salaries on average? To find the company with the highest average salary, we can directly compare the mean salaries. - **Company A**: Mean salary = \$27,000 - **Company B**: Mean salary = \$36,000 (highest average) - **Company C**: Mean salary = \$34,000 - **Company D**: Mean salary = \$35,000 **Conclusion for (b)**: Company B has the highest salaries on average. ### Final Answers: (a) Company C (b) Company B
