Solución

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.
