You can put this solution on YOUR website! The sampled population is normally distributed, with the given information. (Give your answers correct to two decimal places.)
n = 13, x-bar = 28.3, and σ = 6
(a) Find the 0.9 confidence interval for μ.
------
sample mean:: 28.3
ME = 1.645*6/sqrt(13) =2.7372
-------------------
90% CI:: 28.3-2.7372 < u < 28.3+2.7372
-------------------------------------------
(b) Are the assumptions satisfied?
I'll leave that to you. Check your textbook.
