Step 1
The sample variance is calculated as: S^2 = Σ (Xi - Xbar)^2 / (n-1) where Xbar is the sample mean and n is the sample size. Show more…

Let X1, ..., Xm and Y1, ..., Yn be independent random samples from, respectively, a normal N(μ, σ²)-distribution and a normal N(ν, σ²)-distribution. Determine a confidence interval for μ – ν of confidence level 1 – α (i) if σ² is known, (ii) if σ² is unknown.

Let $\bar{x}$ be the observed mean of a random sample of size $n$ from a distribution having mean $\mu$ and known variance $\sigma^{2}$. Find $n$ so that $\bar{x}-\sigma / 4$ to $\bar{x}+\sigma / 4$ is an approximate $95 \%$ confidence interval for $\mu$.
