A preliminary sample of 30 bacteria reveals a sample mean of You would like to estimate the mean lifespan for this species of bacteria to within a margin of error 66 hours with a standard deviation of s = = 5.4 hours. of 0.65 hours at a 98% level of confidence. What sample size should you gather to achieve a 0.65 hour margin of error? Round your answer up to the nearest whole number. n = bacteria
