In the past six weeks, I have bought two different brands of light bulbs. I recorded the amount of hours that each bulb lasted. The three bulbs from BrightSmart lasted 20 hours, 50 hours, & 80 hours. Compute the mean, range, and standard deviation for these BrightSmart light bulbs. The three bulbs that I purchased from Glow-a-Way lasted 100 hours, 40 hours, & 10 hours. Compute the mean, range, and standard deviation for these Glow-a-Way light bulbs.

Draw at least one conclusion from these results. Write a statement about your findings. Next week when I go to buy light bulbs, which brand should I purchase - BrightSmart or Glow-a-Way? Support your answer with mathematical reasoning
