A manufacturer wants to estimate the average lifespan of Tortoises. Sadly, only a small sample is known. The lifetimes in years of five randomly selected animals are 92,110,115,103,98 1. Find a point estimate and a 95% confidence interval estimate of the population average lifetime of the components. The population of lifetimes is assumed to be normal. 2. A fellow researcher wonders whether based upon this information a Tortoise could live to 125 or beyond in Florida. How likely is this to happen?.
