You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 25 bacteria reveals a sample mean of = 70 hours with a standard deviation of s = 6.4 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.55 hours at a 90% level of confidence. What sample size should you gather to achieve a 0.55 hour margin of error? Round your answer up to the nearest whole number. n = bacteria
