A restaurant manager wanted to get a better understanding of the tips her employees earn, so she decided to record the number of patrons her restaurant receives over the course of a week, as well as how many of those patrons left tips of at least 15%. The data she collected is in the table below.DayMonTueWedThuFriSatSunPatrons126106103126153165137Tippers82879368918364Which day of the week has the lowest experimental probability of patrons tipping at least 15%?
For each day, divide the number of tippers by the number of patrons. On Sunday, 64 ÷ 137 ≈ 0.467, or about 46.7%. This is lower than the Saturday rate, 83 ÷ 165 ≈ 50.3%, and the rates for the other days, so Sunday has the lowest experimental probability.
