Let X denote the number of E.coli bacteria in a specific volume of water from a river. Now, a random sample of size 5 yields the following observations on X: 564, 765, 736, 142, 274. Assume that the population sampled is normal. (a) (6 marks) Find the sample mean i and the sample variance sa. (b) (7 marks) Construct a 99% confidence interval for the true mean w of the population. (c) (7 marks) Construct a 98% confidence interval for the true variance o2 of the population.
