Burning Candle

Determine which brand of candle would you buy among three different brands.


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?
