Suppose that a failure of certain component follows the distribution
f(x)=p^x (1-p)^x for x=0,1,and zeros,elsewhere.How many components must
one test in order that the sample mean Xbar will lie within 0.4 of the
true state of nature with probability at least as great as 0.95?
題目有點長，謝謝您耐心看完。
請問這題是和什麼定理有關呢？該怎麼下手？
又，the true state of nature是指什麼啊？
請大家賜教囉！謝謝~
