Question

(5) A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. He wants to construct the 75% confidence interval with a maximum error of 0.1 reproductions per hour. (a) Assuming that the mean is 6.1 reproductions and the variance is known to be 5.76, what is the minimum sample size required for the estimate? Round your answer up to the next integer. (6 points) (b) If one uses Chebyshev's Inequality (Law of Large Numbers) to estimate appropriate sample size instead, what is the minimum sample size to achieve the desired level of confidence? (4 points)
