The owner of a new coffee shop is keeping track of how much each customer spends (in dollars). A random number table was used to generate a random sample of 20 pieces of data. The dot plot below shows the twenty pieces of data.

Based on the data in the dot plot, what would you expect the mean of the sample to be? EXPLAIN YOUR REASONING.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

24
