Employ the given confidence level and sample data to find out a confidence interval for population standard deviation sigma. Suppose that a simple random sample has been chosen from population that has normal distribution.
A simple random sample from population with normal distribution of 107 body temperatures has x(bar)= 99.10F and s=0.62F.
Does population need to be normally distributed for sampling distribution of Xbar to be approximately normally distributed? Explain why? Find sampling distribution of Xbar?
