Question 17 > You are a researcher studying the lifespan of a certain species of bacteria. A preliminary sample of 40 bacteria reveals a sample mean of x = 80 hours with a standard deviation of s = 4.4 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.8 hours at a 98% level of confidence. What sample size should you gather to achieve a 0.8 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
40 bacteria reveals a sample mean of = 80 hours with a standard deviation of s = 4.4 hours.
You would like to estimate the mean lifespan for this species of bacteria to within a margin of error
of 0.8 hours at a 98% level of confidence.
What sample size should you gather to achieve a 0.8 hour margin of error? Round your answer up to
the nearest whole number.
