You suspect one of the die have been modified. You roll the suspected
die 50 times. The observed distribution is provided below,
Value(x) 1 2 3 4 5 6
observed 13 12 10 8 4 3
let p=P(X=1/6),test H0:p<= 1/6 H1:p> 1/6
(a) find the exact p-value
(b) Use normal approximayion to find the p-value
(c) Find a rejection region for test at α=0.05,and the power function.
這題要怎麼做呢?是要用齊一性檢定嗎? 還是 ..... 謝謝!!
