Question
You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 30 bacteria reveals a sample mean of xbar = 66 hours with a standard deviation of s=6.2 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.6 hours at a 99% level of confidence.
