You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 30 bacteria reveals a sample mean of = 64 hours with a standard deviation of s= 5.2 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 90% level of confidence. What sample size should you gather to achieve a 0.6 hour margin of error? Round your answer up to the nearest whole number. n = bacteria

![You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 30 bacteria reveals a sample mean of \(\bar{x} = 64\) hours with a standard deviation of \(s = 5.2\) 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 90% level of confidence.
What sample size should you gather to achieve a 0.6 hour margin of error? Round your answer up to the nearest whole number.
