You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 35 bacteria reveals a sample mean of i = 68 hours with a standard deviation of s = 5.8 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.65 hours at a 95% 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

Question
You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 35
bacteria reveals a sample mean of T = 68 hours with a standard deviation of s = 5.8 hours. You would
like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.65 hours at a
95% 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.
