Question 568529: If light bulbs have lives that are normally distributed with a mean of 2500 hours and a standard deviation of 500 hours, what percentage of light bulbs have a life less than 2500 hours?
You can put this solution on YOUR website! Since the distribution is symmetric about the mean of 2500, this means that 50% of the bulbs will have a life less than 2500 hours.
