可能是小弟比較少碰這種題目 結果一出就卡住了...
Suppose that a coin is biased , and it is know that the average propotion
of heads is one of the three values p=0.2 , 0.3 , or 0.8 . The coin is
tossed repeatedly , and we let X be the number of tosses required to obtain
the first head. To test Ho: p=0.8 , suppose we reject Ho if X≧3 , and
don't reject otherwise.
(a)What is the probability of the Type I error?
(b)What is the probability of Type II error for each of the other two values
of p ?
煩請各位高手指教一下 感謝
