Question 33

Question 30

2.5 / 2.5 pts

Suppose you are doing a goodness-of-fit test with level of significance = 0.05 and k =10 cells. Specifically, you

are testing to see if your data is Unif(0,1); thus, there are no parameters to estimate, and so your g-o-f statistic

has k - 1 degrees of freedom. If it happens that = 12.00, do we ACCEPT (i.e., fail to reject) or REJECT the null

hypothesis of uniformity?

ACCEPT

REJECT

(b) X = U

1/

(c) X = (1/3)U

1/
