Let Xbar be the mean of a random sample of Size 5 from a normal distribution with μ = 0 and σ^2 = 125. Determine c so that Pr(Xbar < c)=0.90.
Please see the attached file for the fully formatted problems.
Solution. As we know that Xbar will follows a normal distribution with mean mu=0 and the standard ...
The Distribution and Probability of Xbar are investigated. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.
