Question

Raquel and Van live in two different cities. As a part of a project, they each record the lowest prices for a gallon of gas at gas stations around their cities on the same day. Raquel’s data show mean = 3.42 and standard deviation = 0.07. Van’s data show mean = 3.78 and standard deviation = 0.23.
Which statement is true about their gas-price data?

A: Raquel’s data are more likely closer to $3.42 than Van’s data are to $3.78.
B: Van’s data are more likely closer to $3.42 than Raquel’s are to $3.78.
C: Raquel’s data are more likely closer to $3.78 than Van’s data are to $3.42.
D: Van’s data are more likely closer to $3.78 than Raquel’s are to $3.42.
