I'm confused on how to solve this problem! How am I supposed to find the difference in mean tip percentage between the three servers? And how many steps should there be?

Chapter 8 Project Most restaurant patrons leave a tip between 15% and 20% of the bill, and some restaurant customers determine the percent tip to leave based on the quality of service. Summary statistics for mean tip percent left between the three servers at the First Crush Bistro in Northern New York coded A, B, and C are given in the table below. Is there a difference in mean tip percentage between the three sewers? Be sure to show all steps of the appropriate test. Server Sample Size Mean Standard Deviation A 60 17.543 5.504 B 65 16.017 3.485 C 32 16.109 3.379 Total 157 16.619 4.386
