Burning Candle

Candle manufacturer companies advertise that their products are better quality and has the longest mean burning time. John decides to select same size candles from three different companies-Bright Candle, Fire Candle, and Shiny Candle- and do an experiment with 15-candle in order to test which company has a better product. He recorded the number of minutes that each candle burned.

Judging from the table, which brand of candle would you recommend to John?
